Massive paranoia there. The guy who used to live opposite me drove an AM and he did just that - drove it.I knew a guy with a 2010-ish Aston. Every month he had to send an engine oil sample to the factory so they could have it analysed for debris etc. Why the actual ***k would you spend a shed load of money on a pretty car that spent more time having oil samples taken than it did being driven on the road?
Making your own engine in the 50s and 60s was fine. Design it, build it, make it run ok, tell the world it it has 240bhp when it really doesn’t, make some money. Doesn’t work like that now.
