I am an owner of this rare one and I absolutely love it.

I found that it has annoyances more than problems. I am a do-it-yourselfer so I do all my own maintenance. There is not much to do beside fluid changes and fuel filter changes.
The only problem I have with it is the hydraulic lifters make a bit of noise, but I'm slowly learning to live with it.

I have some family friends that have had one since new and it has 500,000 miles on it. The only thing major that has been done is a transmission rebuild a few years ago and regular maintenance, of course.

The problem with the AC mostly lies with the potentiometer (sp?) which is in the center of the dash behind the vents and of course takes lots of POOPOO to get to. There has been a post on this site on how to get around it if something goes wrong with it.

Some have said that they have gotten 40mpg out of these vehicles, but I would like to see what math they are using. I've only been able to obtain about 30mpg in straight HWY driving.
