Yes but think what it would have cost on a Ferrari, Bentley etc.
When you wedge the V12 in a slinky thing it gets even worse to find access. I had a bill for the Pheaton V10 which made my eyes water and parts were <£100 as you outline. Still it was only one in 120,000 miles so I figure it was fair use.
It all depends on getting your money's worth. I guess Peter does the mileage to see to that.
