looking at a 91 CRX with 284k miles on it. Dude says he did a motor and tranny swap about 41k ago. (About 100k on the new Civic DX tranny) is this too many miles? Body is in good shape and I’m getting the dude to run a compression test. He’s asking $1800 which seems a little high but I will offer $1100 and see where that goes. Advice is appreciated.
