I have had very good luck with old Oldsmobiles. I happened to come into 2 of them, over the years. Once I bought 23 years ago for 250....must have been at least 12 years old, at the time. It worked perfect, except I needed to sweet talk it to reverse for me....so I pretty much was fine so long as everywhere I went, I could either park on an incline, so reverse possible, via gravity or that no need for reverse was necessary.
I also came into an 18 year old Olds when my grandparents decided they needed a new car. It was almost exactly the same story as above, except I didn't pay a dime for it. I regret selling it, because it still worked and I love my grandparents so much, but I didn't need it, it was taking up room and I could use the cash.
It sounds like I got 2 lemons, but in truth, they both served me well. If you can find an old Olds, with a working transmission, I'd go for it.
Anyway, thats my experience.
