Potential New Owner E55 AMG (W211)
I am seriously considering selling my 1986 Buick Grand National (or trade + cash?) and getting a 2004-2006 E55 AMG. I have had the GN for 10 years now, and it's a great car but frankly, I am a little bored and want a new toy. I am noticing these cars can be found with ~40k-50k miles on them and priced in the mid 20 thousands. A bargain from what I can see.
I am asking for opinions and guidance from anyone that wants to chime in - such as "do's and don'ts" - what cars to watch for and what cars not to consider. What are known issues, and what can I expect. I am aware of the gas tank bulkhead leak recall/issue, but what else to look for?
I am reasonably mechanically savvy - what are maintenance costs such as a set of brake rotors and pads - that sort of thing.
The Turbo Buick message boards have been nothing short of a Godsend of info and help, I am hoping this is a similar arena, so here I am.
Well have at it guys, I know everyone has an opinion! Am I crazy or is this a good idea?
Best Regards,
Chris

On a side note, PM me pictures and details for your Grand National. I have been looking to add one of those for several years.
Brakes actually aren't too bad. A bit over $100/each for front rotors. Front pads run ~$150ish, depending on where you buy and whether you go OEM or aftermarket. Some AMGs use a two piece front rotor priced near $1K, but the E55 is actually reasonable.
Regular service is once/year or every 10K miles. The car takes 9 quarts of Mobil1. Brake fluid is flushed every 24 months. Transmission is serviced at 40K miles (~9 quarts of synthetic fluid - $$) and again whenever you feel guilty about it.
Rubber can cost some money, depending on what you run and how aggessively you drive.
There are some common failure parts. Most are not too expensive, but be sure you are comfortable with the potential cost of the airmatic suspension. The rear struts are very expensive to purchase, not available rebuilt, and very labor intensive to install.
Other than that, tuned cars occasionally blow up their engines; and the tuner never takes responsibility for screwing up the fuel map and melting your pistons. I am a big fan of stock.

I have been scouring threads.. tell me more about airmatic costs and such. The brakes seem reasonable, as do some of the other maintenance items you mentioned.

Anyone that's interested in buying an E55 should be aware that an Airmatic failure can happen anytime.
Now for the good part. Remanufactured struts are $399 from Arnott Industries (vs $1500 from MB). The struts are absolutely one of the easiest jobs I'd ever done on any of my cars. It took me less than 40 minutes to get the old one out and about an hour to get the new one in. I'm sure I could do the whole job in less than an hour next time.

I had a rear strut with a slow ~48 hour leak replaced on my '06 - CPO paid for it. Six months later the new strut failed overnight while the car was sitting in my garage. So CPO paid for it again! IMHO airmatic is the worst part of the ownership experience.
To the original poster - you need to either have a warranty that covers all these common failure areas, or have a ~$5K slush fund at all times. Otherwise you very well may not be able to keep this car on the road. It's not Ferrari expensive, but neither is it for the financially faint of wallet.
Black - The GN is way cool, I am just bored with it. The GNX was a special car (only 547 made) but with a little tuning the regular LC2 3.8 turbo in all the GN and T-Type cars can outrun a GNX easily. Time for a new toy... I would need the $$ from the GN to finance the E55 idea, and I don't have room for both in the garage either...

The electronic trunk seems to be problematic; there are many threads discussing problems with it.
Keyless go seems to break quite a lot too. The Pano roof doesn't seem any less reliable than the regular sunroof, but is astronomically expensive to repair if it does fail. I opted for a car without any of these options.
Nice work!
The Pano roof is awesome, I can't kick one out of my driveway. If the valvecovers are easy to do, I got em. Keyless go always sounded cool, but I don't need it.
Balljoints - problem. Is there an aftermarket balljoint that is stronger; or even a control arm?
