Found a 2nd owner 2000 LR Disco on LetGo for $3600, checked maintenance history and has been taken exceptionally good care of. Also found a $1600 on Craigslist with blown head gaskets, but most other things have been replaced by dealership recently. Is it worth it to repair the LR or just buy the one already functioning? I have a few grand to dump into repairs but I want to spend as little as possible. Both have roughly same mileage.
