Yeh the auction reports are very accurate but ideally you want see what you buying or have good agent. They will do video & detailed images of all points plus you save a lot of money to cover minor fixes.
Ideally you want be trying buy as close to grade 4 as possible & with few extras so have good enough car/parts should ot not be a keeper, any minor marks want be on panels easily replaced/repaired (not rear quarter panels)
Still some super decent old R's going through auction but not regular occurrence so it takes time & bit more money than did couple years ago .
It far safer than buying used ones in uk, but I indeed too would like view in person at auctions.
Process in the UK is very easy for import & registration, plenty of guides online for those who want try. here importing is a big pain & costs about same again as pay for decent R at auction by time finished .
