SL55/63/65/R230 AMG: Average Annual Maintenance costs survey- SL 65
I was offered 50K at local dealer today for mine...after picking up from oil change/new belt service............I told them I would see them in the future.....
I heard the opposite on Bentley GTs from a Bentley service manager in LA as far as reliability.......go figure........depends on perspective I guess....

either way, conti is still a 2nd choice , backup plan.
initially i wanted a w216 cl600, but eventually the idea of cruising with the top down and spending a lot of time lurking this forum has sold me on the beauty of the SL65, so that is still my first choice.
there seems to be quite a large reduction in price when you go from 20-30k miles, down to one that has 40-45k miles (the max i am considering). the difference is around $10-12k.... is there any specific reason for such a large difference for a small amount of miles, or is it just the low mileage owners trying to get the most for their car?
should i be afraid of cars with 40-45k miles on them? of course i will be getting an extended warranty with any of them.
Where are you located? I might entertain an offer
If you find a well cared for car, 10k miles difference is probably not significant.

It seems to me a car that has been driven routinely and had issues which the owner addressed properly is the best deal.
That way I put about 4k-5k miles/yr where otherwise it would be a lot closer to 2K and the car would be idle for many weeks.
The Best of Mercedes & AMG
Question, for those who do their own work, where did you find a repair/service manual for your car? I asked the dealer and they looked at me like a just landed from another plant. I didn't even ask them about a parts manual. I did see some CD's but not sure if they would cover a 2011 SL65. Any direction would be appreciated, even if I could copy files from a web site onto a CD would work for me.
Thanks,
Dave
The only expenses Ive had so far are a bad switch which was intermittently preventing the car from coming out of park, a $900 fix and two routine state inspection/emission and oil change services averaging about $400 each.
Thats $1700 over 15 months, roughly $113/month or $1360/yr. Its currently moth-balled until April and if I make it thru next summer until Sept without any additional problems it will be roughly $850/yr for service.
Potential problems that I so see though are the ABC...twice since I've parked it I've started it and both times I've gotten the ABC too low warning...and Ive notice that when the wheel is turned left and hit the 'up' button on the left side of the steering wheel, the horn blows once.

Last edited by TimsSL65; Dec 26, 2012 at 12:34 PM. Reason: typo
Owned 12 months (car was totalled 3 weeks ago in a rear-end collision)
Drove 14,000 miles (bought at 25K miles, lost at 39K)
$3.4K maintenance (tires, 2x pads/rotors, Svc B, cabin filter)
$3.0K repairs (SRS wiring, SC pulley, SC coolant pump, 3rd brake light)
$3.0K fuel
$2.1K depreciation (at $0.15 per mile)
$1.8K insurance
-----
$13.3K -- about $1 per mile (not including the cost of money)
By the way, the car did a great job protecting me in the accident. I was stopping for traffic on a congested interstate, and the other driver hit me from behind doing around 45 mph. The impact deployed the roll bar and belt pre-tensioners, caved in the trunk, bent the frame and quarter-panels, and twisted the chassis enough to mis-align the roof -- but I walked away with nothing more than a stiff neck for a few days (hopefully no lingering symptoms).

I also computed $ 1.00 a mile for my 65 in an earlier post and I did not count depreciation as it has flattens out a bit the last few years on the 65....
So.....I would say the estimate or calculations at $ 1 a mile is pretty good estimate......
For me, operating costs are important because my car budget competes with my boating budget. Suppose I ignore the costs of fuel, insurance and depreciation (which will be similar for any $50K car). That leaves repairs and maintenance, which cost me $6500/year for the SL55.
So I find myself asking: would a 2003 911 X-50, which sells for the same price and delivers similar driving thrills, cost less to operate? Those engines have a reputation for being bullet-proof. (Although it begs the question, if I get rear-ended in a 911, will I walk away unhurt?)
By the way, I got the depreciation rate for my SL55 by surveying online ads. I looked up 100+ ads for SL55s, plotted the asking price vs. mileage, and fit a trendline through the data. The slope of the trendline is the depreciation rate.
What I found is:
SL55, $1500 per 10k miles
SL65, $2100 per 10k miles
In other words, if you are comparing two SL65s that are similar except one has 10k more miles on the odometer, the higher-mileage car will have an asking price around $2100 less.
(I corrected my previous post, which accidentally used $0.19/mile instead of $0.15/mile.)
I was looking at an '06 S65 (with about 32k miles on it) about 6 months ago, and I was quoted $8,100 for 2 years coverage (I know...it's a different car, but look at the massive, massive price difference).
How in the world did you get an easy care warranty on an SL65 for $1,000 per year??

I did not find the need to mod this car, other than someday having wider rubber in the back for hopes of better traction......
Maintenance on cars that are stock provide a baseline for expenses of owning one of these beasts......
My 1988 Countach, needed new clutch, rear suspension springs and a few other minor things. That bill.....$29,000.
My 1991 Diablo, needed transmission rebuild, new clutch and flywheel. That bill.....$31,000.
Childhood dream cars that eventually turned into something I couldn't enjoy so I sold them.
Now my Bentley GT, I put 45,000 miles on it and it was flawless. Best all around car I have ever owned.
SL65 has the best engine of any car I have driven.
