I have a 52k miles car, when Ieft Scotland IIRC it hadn't reached 46k miles. But fuels not been so cheap for so long it wasn't too bad. The drive back was in the 900-1000 mile region but Volvos have good seats.
I've been so many places and seen so many wonderful places I have never been to before. OK I returned to Madrid, Millau (if only to dine at the Auberge ) and if you are in Salamanca you must eat at La Pachamama. Beautiful food and ran by great folk.
