Think it largely depends how much you crash... And how carefully you build it (use the build tips on the website).
After a season I've stripped a servo horn - that's it & I'm certainly not a great driver but not a terrible one either.
I rebuilt the transmission a few weeks back, I had to replace 1 driveshaft pin & a add 1 shim to each diff, I can't think of a more bulletproof car
I may have lured RogerM to his keyboard with that comment
