When I bought this from the dealer, the only problem it had was rust on the rear chrome, and a malfunctioning headlight control module that would keep the headlights on at night (a problem that was fixed by cleaning pitted contacts that were keeping the lights switched on.)
Needed a new ignition control module at 45000. Not an uncommon problem for a 16 year old car. Costs about $75 bucks for a new one, and took about 20 minutes to replace.
No other maintenance other than general stuff like new brakes, tires, oil changes around 3000-5000 miles.
Dynaride air suspension motor will run way too long, so I unplugged it. I imagine the rear air shocks are shot, but I haven't had to replace them.
The rear tail-light is a one piece assembly. Meaning if you break one tail-light, you replace everything! It's very expensive in the "book" ($745), but can be found in junkyards for about $25-$75 bucks. I've sadly had jerks break two of these tail-lights now! The first time I replaced it with a junkyard find for $25. The second I found one on ebay for $60. The good news is it's easy to remove and install the taillight assembly. There's maybe 12 plastic screws you can remove by hand. 10 minute job tops.
Fantastically reliable and a sharp looking car. Interior is fantastic for anyone looking for comfort. Front wheel drive is awesome in snow areas. I've driven through intense blizzards in this, and it got me home while SUV's and trucks were sliding into ditches all around me. Will start at the lowest temperatures known to man (regularly left out in 9 degree temps and starts quickly and warms fast.)
The other great thing about this car is the cheapness and availability of replacement parts. New parts are cheap and it is very easy to find parts cars in junk yards for stuff like tail-lights and bumpers. I usually peak at the odometers of the junked PA's and they average 200,000 miles!
It's big. A must have for the land yacht lover!
