I have a 9 page invoice from Dec 2014 totaling 8900 dollars because he had the car gone through and re-sealed and new gaskets from head to tail so it wouldn't leak onto his C4S. ( he has a neat lift in one of his garages). in July of 2015 he had the timing belts replaced, all associated stuff with that including all new cooling system ( except radiator) and new drive belts. I am convinced the maintenance has never been deferred.
Shaun, I did pay enough. but i reviewed the receipts from the last three years and paid him less than that total. I am pretty happy.
