SL55/63/65/R230 AMG: Buying a 2003 SL55: Huge financial gamble to go without a warranty?
I am about to pull the trigger on a pristine 2003 SL55 w 21k miles that is no longer under factory warranty.
This is a one owner car who I know personally, and he states he has not had any mechanical issues, except for IC pump failure which he upgraded to an Evosport system afterwards.
I am considering a 3 year extended warranty, which will cost almost $4k. Is it worth it or should I roll the dice? Am I taking a huge financial risk of owning this car without a warranty?
What is known to fail on these car? I read that the ABC suspension fails, but is this due to high mileage or just luck of the draw? How much is it to repair the ABC?
Thanks for the help
In terms of problem areas I did have a small ABC leak that was repaired under warranty and has been fine since. My sense of the forum comments is that ABC leaks aren't all that common but failures with the ABC sensors and pumps are somewhat more common. That said, i don't know whether the mean time between failure is 50,000 miles or 150,000 miles. I'm at 43,000 miles and hoping for the best.
I did have the intercooler pump failure that everyone seems to experience sooner or later. Mine happened around 30,000 miles.
I also had a Command unit that would crash every 30 minutes or so. That problem was eventually fixed by removing some after-market cables that a previous owner had wired into the antenna system.
Other than those issues the car has been reliable, which is part of the reason I felt comfortable running without an extended warranty. The other part of the reason is, extended warranties are priced to be profitable and cash flow positive for the warranty provider. Rather than taking the certain expense of the extended warranty I felt comfortable keeping the money and taking my chances that my expected repair costs would be less. A more risk averse person could very rationally choose not to take that chance.
So there's no right or wrong answer on this. It's basically a risk tolerence decision.
100.00 deductible. Way i look at it one big failure and that will pay for itself, its more of an insurance policy than a warranty. BUT like my mercedes service manager told me when i took mine in for first service, he said do ALL recommended services through mercedes, make sure you have documentation of this and if you go through MB of course they will have it in their computer. If yo uhave done your due dilligence in keeping the car tuned and serviced he said you are a LOT more likely to get all your claims covered, vs. a guy who hasn't had his sl serviced in 25k miles by a dealer and blows out the super charger or something.
i research and researched, i found it about 50/50 on those who said do it or don't do it, some said put that money in a savings account, some said do it. I look at it like this, i'll feel more comfortable driving the car harder and having more fun with it knowing im "insured" even for just a little, plus it has to help as a selling point if you go to sell the car in 3 years or so to put "2 years left on warranty"

The Best of Mercedes & AMG
I also just stumbled across this thread which has good things to say about the Ford Cobra pump, which apparently is a Bosch pump that flows higher than the Bosch pumps that Mercedes uses: https://mbworld.org/forums/sl55-amg-sl63-amg-sl65-amg-r230/211741-intercooler-pump-replacement.html. I don't know anything more than what's in that thread but it sounds promsing.
Good luck! If you use something other than the OEM unit I, for one, would be grateful to get your impressions of the pump that you wind up using.
Think of it this way. $4K (or an average of $1,333 per year) to protect yourself from digging potentially DEEP (maybe likely) in your wallet on a car with thousands of parts/electronics that could go bad on a car with almost 500 hp.
No brainer. Buy the warrantee (shop around, too). Just call other dealers and get a quote.

I have tracked the car. Taken it on long trips and everything in between. It has also been the test bed for allot of our 55K software. The only problems in 5 years have been an IC pump, some tire pressure sensors and an AC compressor.
These are/were expensive cars. Just because they are a great used car bargain, does not mean that the cost to play is cheap. Servicing them is relatively easy and fairly cheap, but they need to be maintained and not neglected. Deferred maintenance and repairs will come back to haunt. I see this with guys who buy their first Ferrari. When they take it in for a major service and are told that it will cost $8K, many will sell the car or just neglect them.
If you take care of the SL55, it will take care of you.

Have you had to use it yet and did they pay?
Thanks.........Geno


You have to have a warranty on these cars, its really great peace of mind. Especially 2003 55s!!!
One major hit could easily cost 10k. Plus when you sell its a huge bonus to the potential new owner.

i got the guys number at work, he was highly recommened on this forum and on benzworld. I just had to use it the other day.....i had the 40k mile service completed and the valve covers were leaking they said, 100.00 deductible and the insurance covered the other 600 and change. Service manager just called them and they immediately approved it, waited two days for dealer to clear funds and they fixed it
SO GLAD i got the damn warranty
