That's correct but a weld isn't as strong on the lotus as under severe stress the weld would crack (not good) but atleast as far as the Lotus Elise is concerned glue and rivets on each join just bent. I saw a programme a while back on it.
Back on topic about the engine wear, LFS on the PC had a similar realsim as far as treating the engine goes. If you reved past the red line even in a short 5 lap race on most gear changes the engine would stutter/missfire but if you kept it within it ran just fine.
I still think an option to restore the lost performance is needed by way of repair or replacement as you would be a bit worried about dmageing hard to obtain cars.
Maybe PD should include a service dept with more emphasis on regular servicing for cars in a higer state of tune either race or street and like 1 service evey 3 years for a Volvo
