All this talk of Corvettes being the best performance for the money, LoL... No. Unbelievable performance for the many absolutely, right up there, but just a small step below the real boys. I mean even the new Camaro ZL1 comes real close on track but just cannot handle as tight. Hell a Hellcat or Demon is more interesting overall, just be very careful cause it wants to kill you. The real competitors would be a BMW M4 and M2 competition packs. They handle significantly better than anything GM can manage and the interior/tech is all far superior as well. Of course BMW comes with it's own stereotypes, but hey the Vettes sure do cover up for something small as well!
I'd have to do research and test drive to determine which car has the best performance for the money. But that is not my main concern.
Again, I'm not a fan of European cars in general. Many seem to think that euro cars have better build quality but I think they are way overpriced and outrageously expensive to maintain. Friends of mine who own euro cars often complain about service issues, especially after 100,000 miles. BMW may make a sports car that has advantages over a Corvette but quite frankly BMW styling reminds me of a shoebox and that's not what I'm looking for. I would say the same for Mopars. I've owned one Chrysler product in my life and it was the biggest sh*tbox ever. Got rid of it after 3 years and many service issues. None of those models you mentioned come anywhere close to the styling of the Corvette.
If I were to look overseas for a sports car I would look to Japan over anything from Europe.
