SL55/63/65/R230 AMG: Average Annual Maintenance costs survey- SL 65
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
Posted below is my history with my car to date - this was a post on AMG Private Lounge I posted previously.....
My AMG is just fantastic when it runs, but not that reliable relative to being in the shop with 50K miles on the clock......have driven it 23k in 4 years.......
My Easy Care Warranty, which cost 4K for 4 years up to 60K on the car has covered
Update = $ 8.8k)Ignition module - $ 1K
Intercooler motor - $.5K
Coil Pack - $ 1.2K
Truck soft close (PSE Pump/Latch) - $ 1.5 K Total expense -
MAP sensor - .1K
Front left strut - $ 1.1K
ABC Line - $ 2.128K
Rear Main Seal - $ 1.286K
My out of pocket - maintenance costs....$ 6.2
New Plugs - .4K
Tires - 1.1K
Glove Box fix - .1K Total expense
Oil changes (3) - .7K
Transmission service - .1K
2 front rotors - 2K
Wipers - .1K
Suspension creak T Service Bulletin (2X) - .4K
Warranty deductibles - .7K
Tensioner and V-belt - .4K
Trunk struts - .1K
Battery - .1K
Operating costs - Gas @ $ 3.70 gal. (16 MPG) and Insurance @ $ 80 month - 8.9
Grand total = $ 23.9 K/approx.
Approx. $1.04 cost per mile on operating costs........................warranty basically paid for repairs in advance with my money and I am $ 4.9 K ahead on warranty approx. with 3 months to go.....depreciation based on my purchase price was another 23K, so double for the cost of ownership per mile to $ approximately $ 2.08.............
Had past year with no repairs in 5,000 miles, only regular maintenance until this week with ABC line and Rear Main Seal issues.......
Time to really evaluate a trade.............re-upping warranty is $ 3K for 2 years.............tough to replace this car unless I bought another used one with a warranty........once you drive a V-12 convertible........tough to beat or replace.....

so far, i've only had minor items that have needed attention and my fidelity platinum warranty has taken care of them. my fingers remained crossed...
after driving fun cars since i was young (boss 302, 240z, 911, e55, etc) i never thought i'd experience a car that becomes part of me like the 65 does. it is like no other, esp with the top stowed. i believe i got a great deal on it; 05 in excellent shape, 34k mi, 2+ yrs left on platinum warranty, oem and bbbs-gt wheels, 2 sets of tires, etc., etc., etc., for $45k.
previous owner had all the records; nothing major, mainly scheduled maintenance, and garaged the car during winter months. he took great care of it.
now - she, the 65, has a good record, looks as hot as kim bassinger in 9 1/2 weeks, stops car affectionatos in their tracks, and runs like the bulls of pamplona (only stronger)...so, "if" she costs ~$1-2/mi is she worth it to me? I'd have no other! V-12 biturbo rocks...

thanks again for your participation...

I got a Fidelity Platinum for 4500 to cover the 5 years i intend to own the car.
I looked for 2 years at all kinds of cars from vipers to GTRs,Z06s Etc drove them all and pulled the trigger on the 65.
Im in love with the car, i have not had any problems with it other then the pulse/air seats stopped working and i have not went to the dealer with it yet.
I checked fuses etc but nothing yet.
The first owner had the trunk locking thing changed under warranty but i herd that was one of the common problems with this car anyhow.
As far as the ABC system i did hydraulics in the Navy and from looking over this system and talking to my tech at the dealer, i asked them how many times does anyone come in and have the ABC system filter and fluid changed? He said NEVER have they done one single one as a proactive thing.
My question is why? The system is pumping this oil threw the system and it gets dirty and breaks down.The system has a filter so what is the filter there for if not to ever be changed?
Maybe I'm nuts i don't know but it can't hurt to try.I know it don't take but a spec of dirt to get stuck in the valve body and cuse it to leak down.
I hear the motors are bullet proof so I'm not worried.I plan on 2018 to trade or sell this one and pick up a 2013 or 2014 depending on what i find at that time.
I would love to keep the car and just have 2 but seeing this thread i think that would be kinda foolish..LOL
The older abc filters were 10 micron and the new ones are 3 micron.
Im going to pull out the fluid with a clean turkey baster and replace the filter.
The filter is easy easy to change.
I checked the fluid and it seems clean but could use a refresh.
I did the same thing on my Nissan truck just a drain and fill on the tranny.
I know it may seem like overkill but i can do it for about 90 bucks thats good piece of mind on such an exotic system , it can't hurt keeping the fluid fresh and clean.

Im also sure they flushed out the whole system i guess that takes more time.
My car only has 17k miles so I'm going to just do a filter and drain the tank and refill with fresh fluid.
The Best of Mercedes & AMG
I have been new car shopping but once I get back into the 65 after the various test drives, nothing really compares from a smooth and fast ride perspective which is what everyday driving is really most about……………navigation system is about only real complaint, but it is almost a decade old now, so that is expected, so the iPhone GPS does the trick…..
Porsches are getting way way overpriced now for what they are……….Panamera just too ugly……….GTs and Turbos too over the top……….
Looked at pre-owned Bentley GTCs and GTs, and the 599 and California Ferrari seriously, but the 65 gives a better balance of luxury, versatility, value and performance which is awfully hard to beat……
The SLS roadster would be a nice option, but I will wait for the right pre-owned one to buy at the right price, if I sell the 65……….

I've worked on high end and exotic cars my entire adult life. The R230 is absolutely amazing. The level of quality, the performance of the AMG cars, everything about the car is very impressive.
I do all my own work on the car. One of the amazing things about the R230 (at least the V8 cars I've never worked on a V12) is it's quite easy to work on. Since purchasing I've done the following:
Brake pads/rotors front and rear
All 3 ABC Accumulators (preventive maintenance)
Rebuilt both ABC Valve Block's (preventive maintenance)
Flushed and filled ABC Fluid and filter change *Preventive maintenance)
Fuel Filter
Spark Plugs and Wires
Oil Change
Smarttop module (upgrade)
Transmission Mount (preventative)
Drive Shaft Flex Donuts (preventative)
Engine Mounts (one was leaking)
Remove resonators (upgrade)
Front Control arms (bad bushings)
New Tires
That's all I can find to do to the car. Much of it was preventative but I plant to keep the car for quite a while. All said parts were $2500 tires ran an additional $1200. The work was all performed in my garage (on a lift) over two weekends.
I bought my car with 96,000 miles one owner older lady who commuted from Phoenix to LA. I purposely bought a higher mileage well cared for car. I just turned 100,000 miles and the car still feels like new. I drive the car almost every day sans a project requiring my truck. I commute 60 miles every day. At 100,000 miles a German car is barely broken in. GERMAN CARS HATE TO SIT!!!! Spending decades around Audi's, Porsche's, etc the absolute worse thing for a German car is to sit around! That is when they start to develop issues! My car has all the original ABC lines/hoses and not one is showing any sign of weeping.
The gentleman who compared maintenance costs of a SL vs. other exotics, especially of similar performance to a AMG car, is right on. There is nothing (short of a Corvette but that is a completely different car) that will deliver this level of performance for the price. And the build quality, comfort and quality of components of the Mercedes is in an entirely different class.
If you cannot or choose not to do your own work find a good Indy or, get a warranty.
THE BEST MONEY you can spend on a R230 in terms of preventive maintenance is:
KEEP YOUR ABC FLUID FRESH!!!!! No question this is a major reason there are valve block, strut failures, etc. Hydraulic fluid breaks down over time and will eat/corrode seals and hoses. A flush also removes the dirt and debris that accumulates with time.
I will flush my fluid and change my filter every 20,000 miles. It's as easy as changing the oil. No Star Diagnostic necessary!
If you choose to have an Indy work on your car find a good one and treat them right! Bring them cookies (no kidding!) and a bottle of wine around the holidays. You want to become the guy they all know by name and yell "hi" to when you enter the shop. Like any business there is discretion to be had when it's time to write up the bill. You want to be one of the "good guys".

It seems to me like most of the repairs for the SL65 are ones that someone with basic mechanical aptitude willing to spin a wrench could do.
