I have had a '94 D-90 since new. I haven't had too much trouble with it, at least no more or less than most other car. They do have some minor build quality issues that I think should have been better. For example the rear mat in the back of my car dried out and fell apart. It is now covered with rhino liner instead. The center console box should have been better built. Mine has been replaced. I lived in southwest Colorado the majority of the time I have owned the car, but it has had a 4 year stint on the east coast. And I am seeing signs of rust where the metal roll cage bolts onto the aluminum body. Other small parts are rusting, check out the stuff on the back door that hold the wheel on. I just developed a leak in my rear differential. Hmm that is all I can think of right now from that standpoint.
I used it for a daily driver for 11 years. It is better as a second car. Highway driving is miserable (too loud). But the seating position is really comfortable. I don't have AC in mine, so summer driving with the top on is HOT if you are not moving. Moving with the rear windows out and the driver windows open is fine (and I lived in Florida for a summer). The heat is fine in the winter even with the soft top. Off roading I have yet to reach the cars limits before I reached my own. I've driven it in the southwest mountains of Colorado, and in Moab on several occasions. Here is a pic from one of the more mild trips the truck has been on. If you have any other questions and want an honest answer feel free to ask
