Tips on purchasing a 2003+ E55 AMG
I am mostly looking at some on autotrader/craigslist that are under the $20,000 mark, as I may need to pay cash. But I know, "you get what you pay for", so I want to be cautious first and who else is better to ask than you guys. Some questions I have that you could hopefully help me with:
- If I am buying from a private owner, what type of questions should I ask about the car? Like costly maintenance that a 80,000 - 100,000 mile E55 will soon need or should have been done already.
- Is there a best place to purchase an aftermarket warranty? I don't want to be spending $8,000 when the suspension or something fails. So I'm hoping I can get a bumber to bumper warranty somewhere for $2000-$3000. Are there any requirements to qualify for the warranty that I should look out for?
- Any other reason you think it would be a bad idea to purchase one of the E55's that are around $16-$17,000 over the ones that are in the mid $20,000's?
If there is a thread on here that answers things like this I'm sorry I tried looking first.
Thanks
Based on the information I have read in the past couple months, the most common problems with E55 are:
1- Supercharger pulley/clutch bearing failure. If detected early, very easy and cheap to fix, but will need to change the whole pulley if left unnoticed which can cost you about $600
2- IC pump failure. This shuts down the supercharger after couple strong runs. Easy to fix as well cost about 700 with replacing H/E as well.
3- Airmatic failure which can be expensive and can fail anytime and cost about 500 a piece w/o installation.
4- Fuel Pump leak. Many e55’s have this problem and some say it is easy fix but others still have problems.
5- Due to the high tq these cars have, motor mounts and possibly trans mounts fail regularly.
6- If the car has dynamic seats, the motor tend to fail.
There are other problems, some costing a lot to fix like transmission failure but they are not as common. I don’t think high mileage would be an issue as long as all the maintenance has been done on time and you got to remember although these cars are cheap now, they are still AMG cars with high original price tag and high price parts.
Before you buy take the car, get PPI which cost about $250 and that will tell you extacly the condition of the car. A good warranty cost about 3-4K and I don’t think you can find a good company that covers many parts around 2k. I have searched for warranty before I make a move and buy e55 and found some companies give you a very high quote for high mileage e55 (03-04 with 70,xxx or higher). I think if you can work on cars yourself, warranty isn’t that necessary as most of the stuff are easy to do and there are many DIY available here on the forum.
Hope the Info helps!

I don't mind paying a $700 repair bill every now and then, and I like to work on cars (although I've never worked on anything like an AMG Mercedes), but I have heard of the suspension going on these cars and it costing around $8,000? That's something I don't want to get stuck with.

I buy over 20 AMG cars a year, but look at 40+, and half of those get thrown back in the pond for one reason or another, usually due to poor PPI results.
Make sure to run carfax and autocheck, and to get PPI shop to do basic cosmetic inspection (paint/body, frame, unibody, etc) to make sure it's in good shape there as well. Nothing worse than buying a car and in a year the clearcoat is peeling because you did not know one side was repainted.
As far as warranties, 2004 will be OK, 2003 is very difficult to get full coverage on since it's 2012 and the car is considered 9 years old according to warranty company calendars. Usually they'll go back 7 years for full coverage. Try to stay under 70K miles to qualify for full coverage.
No way will you get a good company to give you an exclusionary warranty on a higher mile E55 for $2K or even $3K. Plan to spend $4K+ for 3 or 4 years, with term and price based on mileage of car.
I think the E55 has ABC suspension, which is more problematic and expensive to repair than airmatic. So a warranty that covers the ABC system is important, and only the top level plans do. Look at it this way....if you spend $17K on a car that does not qualify for top level coverage, and then spend $3K in ABC repairs, you could have spent $20K on a lower mile car that would have qualified and wound up in a better place.
Good luck! If you need help finding a car or warranty feel free to email me at brucem105@comcast.net.

My input - stay away from modified/tuned cars. The E55 engine and transmission are quite solid, only modified cars blow up in specatcular (and very expensive) ways.
Let me correct a statement Bruce made - the E55 has airmatic suspension, not ABC. It costs about $3K to replace both rear struts (about $2K for one), and $1K-$1.5K fro front struts, depending on whether you use OEM or remanufactured parts. The $8K number does not apply to the E class.

the current stickies are slated more toward experience owners not newbies - which is understandable due to the age of these cars...

I have always loved the E55 but I don't like the exhaust sound or the fact that it's only available in automatic. Plus it's going to be hard for me to find a warranty if it has high mileage.
M5 sounds amazing (especially with exhaust) and I can get a manual. Newer year, less miles, easy to get a warranty. And only $4-5k more (insanity). Damn it I really can't decide. I've read up on the E55 so much and like it more but I think the M5 will be better for me it being more of a drivers car.

M5 REALLY needs a warranty - transmission horror stories if you read on the M5 forums. At least with the MB the most expensive parts (engine, transmission) are near bulletproof which is not the case with the M5.
Good luck either way. Tough choice.

There are many of them under 30k now with 80,000+ miles. All I know so far is that the clutch will go around 90k.
Thing is, I am a drag racer so that is why I prefer the E55 because of its torque and easy modding. But the M5 can be had in a manual transmission so

I have well over 75 E60 M5/M6's covered under warranties I've sold. The claims are unreal, and they make the AMG Benzes look like Hondas. VANOS is $8K+, SMG pump is $7K+, iDrive is $3K, and then there are other problems that are NOT cheap. I would not own an E60 M-car without a warranty in a million years.
Very few have gone to full term on their extended warranties, unlike some of the W211 AMGs. But I can tell you that the average loss ratio on an E55 with an exclusionary plan is approaching 80% (meaning the average car will pay out 80% of its premium in claims), but the E60 M-car is projected to top 100%. Once a car tops 100%, it gets dropped or surcharged. I just saw a $32K engine payout on one of them....talk about getting your money's worth on a $4K warranty!

I was not referring to routine mechanical repairs like the ones you reference.
I expect modified cars have seen much more full throttle & redline than stock cars. I'll take stock anyday.
I just got it and 2 days later I heard a noise from the compressor. It was a pulley making a sound. I'm not sure what's the proper name for this pulley, but my mechanic told me that this pulley isn't sold by itself. Either it goes with a kit which is 1500$, or I can buy a used compressor for around 1000$. Not sure whether he is lying or not.
He also told me that it needs a transmission tune up (200$)...
BRAKE sensor is ON but my brakes are still good. That to fix is around 300$.
Need ru help guys, can't trust no one these days...
