Thanks for all the good wishes.
Had a nice day, drove over to Ilkley in the Z4, dropped the car off and had a very indulgent lunch in Bettys. Collected the Z4 and drove home with a nice new MoT so that's all 3 done now for another year. 40 miles is quite a way to go but I've been using the guy for over 5 years and the Z4 was in good company as another of his regulars had brought in a 2000 Aston Martin for its MoT.
