In my experience if your looking fir a specific second hand car then it's well worth the travel.... Your example is a saving of £1500, so it might cost £100 to get it... Seems like a no brainer to me. I went all the way to Bournemouth to pick up a mini and I got it for nearly half the price I would have paid in Scotland... I would say concentrate on the spec and price and then look at distance. If it's from a mini dealer then they can ship so work that into the deal
