I would. And Dave's made the point I would have made.
We're all in GTIs and Ed30s - cars built for fun, that we all love driving, don't we? What better excuse for a little road trip than this?!
I could understand if we were all say fishing enthusiasts (random example for the sake of argument) - travelling the length of the country for some fishing tackle wouldn't appeal to us in the slightest. It would be a chore. But to see this as a chore when you're a car nut would be to completely miss the point!
Take your other half or a mate, get a hotel, plan some other stuff to get in while you're down there, some shopping and a nice meal out maybe, then enjoy the drive back getting some proper enjoyment out of your investment in the remap.
Surely we're not all in this to enjoy looking at our cars sat on the drive!
