At 70,000 miles it started leaking oil; was told the problem was blowby, which can only be fixed by replacing engine (I have been told by more than one mechanic that this is fairly common for Caravans like mine). I've been able to live with the oil leak, but now at 133,000 miles the transmission is going out. Talking with other caravan owners, transmission problems are very common. Before buying an older Caravan I would make sure to have a mechanic check out the transmission carefully.
All in all it's been a good car and pretty reliable.
