150miles each way, twice.
Travelled from Essex to Lexus Derby and was glad I did. There was one closer in Lexus Ipswich, but it didn't have many options, and it was seeing what the current prices were when I picked up my IS300h from service that sparked my interest.
I had to travel to Sussex for my Supra which was not so far, but I've always been willing to travel for the right car, but you have to accept that sometimes you can be disappointed.
