1984 Cadillac Biarritz--any owners out there?

I'm looking for a car or two to buy this summer for tinkering around with. I like the looks of the early 80's Cadillac Eldorado Biarritzs and there are some in my neck of the woods at a low price. I am wondering if anyone has experience with them..... repair costs, reliability, fun of driving, etc. Thanks.
