Cant remember the cost of a Viva clutch, but I remember I could eventually change one in under an hour , as I burnt out 4 of them and broke 3 gearboxes in not much more than a year.
The difference between a 2 stroke Japanese motorbike and a Viva took a while to register in my teenage brain.
30 years ago, a friend collected me for some help with a job. On the way, he stopped at one of the fast fit clutch places and handed over the keys. We walked to the caff 200m up the road and had coffee. When we got back to the garage after about 15 minutes the car was in the same spot. We walked in, and the receptionist gave him the car keys in exchange for £50. That was about £5 more than he'd have spent on just buying the clutch. My record for a Capri clutch is about 40minutes, with the car on ramps in the street. That's not a job I'd do now.
