Absolutely 100% , Couldn't agree more.
Part of the reason I don't get many comebacks is because there is always something needs fetching from Inverness, (120 mile round trip from me), so apart from my PDI, 90% of my Cars do that trip before getting sold .....................
I always look at each Car with the question "Would I be happy for my Kids / GF to drive it from here to Kent and back ??" and if the answer is yes then it is ready for sale
I don't sell the Volume some guys do, 6 a month, so it works for me, I know it's not practical for guys down south, jeez it would probably take you a week to drive just one Car 120 miles with all the traffic
Fact is though, with my situation, a trip to IV, a trip to Kyle for MOT Test, and a run to the Take Away / Shops and they have all done around 200 miles before I sell 'em
