I'm looking at motors at the moment for Mrs Greedy (just off to Dartford to see an E220
- joke), and they basically all need and alloy wheel refurb, some paint touch up, gearbox oil change, possible cambelt water pump, 2 or more tyres etc.
Speaking of the 400 mile round trip, I wasn't think of 400 miles for sight seeing. I was thinking 200 miles with cash in the pocket and your mate in the passenger seat, having already grilled the owner over the phone about history specifics, tyre condition, arch rust etc. Then if it checks out, do the deal there and then and you or mate drive it back.
And even if it's not that one, same protocol with a different one. Trying to do the deal and drop of the hire car in the same journey is asking for all sorts of complications imo.
