Enough to make you paranoid. I lost count of the number of belt changes I had done on my first GTV - a TS - and I always sprung for the variator as well ('tho reading elsewhere on this site it wasn't nessesary).
Bought my 01 V6 last month from Veloces, and asked them to do a cambelt change before I picked the car up even though it wasn't due - just in case. It was only 5k since the last one, but it was 5 years. I've now run and checked the invoice to make sure they did the idlers - and they did, the beauties.
You experts out there - given the above pictures, is it worth getting the belt inspected every service?
