I don't know about Beetles, but IIRC there was a race around that time where it was NASCAR regulars versus European motors on an oval and it was somewhat close (?), and with a bit of googling a Jaaaaaaaaaaaaaag won a race in '54.
Entering a NASCAR Strictly Stock race used to be much easier.
Jag ought to make a return to NASCAR. They seem to have some pretty slick sedans these days. It might be a pretty useful marketing tool to get their name back into the minds of Americans as well.
Wouldn't an ALMS programme (and IIRC they are about to start one) be better for promoting their cars against more similar competition to their road cars? EDIT : Yes, Rocketsports are about to run a XKR in GT2 starting at PLM.
It would be pointless however, with dwindling grids, except for Sebring/Petit LM (with the class merge (LMP/GT) next year, it's looking ominously like Grand-Am)
Unless they are to promote the E-type, yes. They should probably spend their money on ads at golf tournaments instead.
(maybe I should not taunt NASCAR for being the amish of motorsport but I can't help myself)
