General Comments:

If you want to own a 55, you've got to do your homework well. Choose the best car on the market that has been well looked after. A neglected AMG car is big money to fix. The main culprits are the ABC system and roof system. Once these are properly sorted, there's nothing much else to go wrong. Just keep checking oils, coolant, etc... all the time. I do it before every drive.

On the plus side, there's still nothing like it on the road. It's hard to believe this car is almost 16 years old. Even the old Bose still sounds good. Take the TC off and enjoy 500+ hp. I removed the cats and dropped in a pair of K&Ns... The sound alone is pure AMG/NASCAR... I wait for tunnels to drop down to second gear.

Will I keep it? I think so, since MB is stopping the SL range (so I heard). As long as I can keep it on the road, it will stay. For the money, there's nothing you can buy that has this exclusivity.
