The Giro D'Italia is a multi-day event, Villeneuve drove some of the stages before he was called back to his F1 duties, story here:

Great build Gary. My understanding too is that the car was destroyed but apparently there is debate about that. Lee Moody has built a replica.

Some but not much.
I corrected the roll cage to match the actual race car
Added some more detail to the interior and engine bay
Used aftermarket decals
But that is about it. Revell has issued the '68 Corvette in multiple versions but they are all very similar and build up well.
