My mom has a 97 Ford Taurus with 60k that she bought for $950, worked well for over 2 years. The car is worth about $2k. The transmission is shot and think it will be about $1.5k to replace with re-manufactured unit.

I told her it probably doesn't make sense to spend near the cars value on repairs.
I am thinking a 2000+ Crown Vic with 100k-ish miles on it for the $2k price range. She doesn't drive a lot, 10 miles each way to work.
Anything else I should consider that will be reliable?
