SL55/63/65/R230 AMG: SL55 or SL65- I am in the market
The SL55 is more power than I will ever need, and this car will really be an extra fair weather driver that my 25 year old daughter may get the chance to drive every once in a while. Any advice would be welcomed I am getting one soon no one can talk me out of that, once I get a car into my head I have to buy it and ready for this one yesterday







The 65 has a nicer interior as it is nappa leather instead of MB tex, but that's the only non-performance item that isn't the same between the two that's significantly better on the 65 vs the 55 (the wheels and front bumper are different on the 65, but the majority of people probably would not notice this difference)
A 65 or a 55 in the hands of an experienced or irresponsible driver (which is a lot of 25 year olds, though yours might not be. She might have a bonehead boyfriend that convinces her to let him drive though) is dangerous.



-higher insurance
-higher property taxes
-front rotors that are 1k each
-8 more spark plugs (each cylinder has 2 in both the v8 and v12)
-coil packs that go bad on the v12 (its suggested you buy a set with a lifetime warranty from a place like advance auto parts as you will be replacing them often)
-motor mounts in the v12 require the entire engine cradle to be dropped and is a 20+ hour job, so multiple whatever the shop labor rate you use times at least 20 to get the motor mounts done on the v12. The motor mounts on these wear out due to the high amount of torque the v12 makes.
most other maint will be the same for things like the convert top actuators wearing out (designed for 10k actuations), ABC suspension maintenance (like needing to rebuild the valve blocks & replace the accumulators at about every 10 years or 100k), and SBC brake replacement (which occurs after the brake pedal has been pushed 300k times). Most aftermarket warranties will not cover these items, especially the ABC suspension system.
Just know that one of the reasons these cars have become so cheap relative to their MSRP is that maintenance costs can add up fast if you are having someone else do the work.

I love my 2007 SL55 . I change all the fluids religiously. I would recommend changing the ABC system ASAP after your purchase.
Good luck with your ultimate purchase.
I have never owned a SL65, but can tell you the SL55 will have all the power you need. If the power of the SL55 is not enough for you, you can always do performance upgrades. The AMG 55 motor is a very good platform for doing this, while retaining the stock like attitudes.
The 2007/2008 SL55's were the end of the production and have more goodies than the previous years. Study the differences when you are looking to see what suits your needs.



The 07/08 55 had a more efficient supercharger that produced slightly more boast along with a larger 80mm TB. this is why they are rated as having more power. The supposed upgrades to the ABC system are minimal & if memory serves me right the rotors on a 07/08 55 are way more than on the 03-06. The tail lights I think are also the newer version in the 07/08.

65 Amgs and the Audi V12TDI are 738 lb and tied for 9th and the Pagani Huayura at 740 for 8th which is basically the same engine and we all know these cars were limited do to factory's concerns about the transmission not taking any more torque. Everything else on that list is 400k, 800, 1 mill+ with the exception of the Fisker Karma which is 981 at 0 rpm which I'm guessing is on full battery mode for that 15-20 miles the car can do without gas.
Literally I had more fun with the 65 engine then the 55 and it is worth the extra expense if you can afford it, not really surprised why mercedes didn't do much to the M279 engine except turbo change and some minor modification but engine internals are still the same. The engine is pretty good even though its now a 10+ year old platform for the most part.
. I have a 2007 SL55 Performance Pack. This site really helped me with my decision and the price I paid for mine was excellent (bought from Alberta that was a distressed Province in January from the low cost of oil). I love how fast my car is. Love the comfort. Love the top down cruising with the wife. Been great. I love fast cars so if it was a bit faster, yeah that would be awesome. That would be the SL65
There were none around for the price I wanted to pay, so I am just loving my SL55 030 Really, there is no wrong choice...

The aftermarket warranty and a garage that knows the insurers is well worth it for piece of mind.
