Ive never done this so its my 1st time. How much woukd recovery cost me to glasgow?
Buy one that drives, buy a
return train ticket as close as you can get to it, go see it, if it's good, get insurance day cover on it and drive it home, if it's bad, get back on the train and use the other half of it.
If this is your first time pulling this sort of nonsense - get one that can be driven back, unless you have a licence to tow, a big enough tow car with a towbar and access to rent/borrow/beg a trailer.
Commercial recovery outfits charge commercial money to move expensive cars around.
