I have had to replace the motor and some bulbs. The rear doors don't open, and the locks have a short.
It has been a very good vehicle besides the motor but I bought it cheap so it was very much worth it to replace it.The 4.3Ls are very powerful, nice to tow in and also comfy for up to 8 people. A high step in height and also since it is built on truck platform id does not have as a refined ride as most front wheel drive minivans.
I have a 1988 GMC Safari, it's been a very good van.
The motor never gave me any problems.
The only thing's I had to fix were the two speakers in the back doors, I had to get it painted, and a new radio. Besides that it's been a great van.
