Car runs and drives very well, ust took it on a 300 miles round trip over the weekend, he only flaw that I am aware of is a high idle in neutral or park and the clear coat on trunk is starting to crack and could use a good detail.
This car sold for $88k back in 1991 one of the most expensive cars available at the time, t has tons of neat features especially for almost a 30 year old vehicle.
This vehicle was part of an estate that I purchased, have owned it for about 2 months now and drive it as often as I can because it is such a joy to drive, have had no problems with it never left me stranded and it always turns heads. Through some research I have found that this is a pretty rare car, ADA is 10,000 for low value and 18,000 for high value.
Please feel free to ask any questions I will do my best to answer them
