Audi Cambelt & MOT offer

My A3 is up for its cam belt soon after hitting 5 years old (albeit only on 37k!)

I'm looking at who to use currently and I seem to have two options, local Indy and Audi.

Indy wants £385 for belt and pump, (Non Genuine Audi parts)
Audi want £599 for belt and pump and that has free MOT's for life as well (Transferrable to next owner!)

The car has a full Audi service history to date and its next service will be Audi too (took them up on the 2 services for £299 offer!)

My local indy seem to be hit and miss, I have asked for a price with genuine Audi parts (Audi will price match them!), but in the past when i looked at getting my brakes done, the Indy was actually significantly more expensive! Their hourly rate is pretty horrific for an Indy I thought at £77 + VAT per hour.. which makes me question the quality of the products to be quite so cheap!

Has anyone taken them (Audi) up with the cam belt and then used the free MOT's for life aspect?

I have asked them for a genuine price parts via e-mail, as they are opposite the Audi dealership and Audi are pretty good in price matching them anyway

Winning, priced matched local to £425!

Yeah pretty happy.

Cambelt all tensioners etc etc for £253 less than list, all it took was one email!
