Nope, I also agree. Save the longitudinal V8's for the SLC's/GT40's/etc.
I see the GTA to be the baby brother to the SL-C. Transverse IL4's and V6's should be the name of the day.
Thanks for chiming in regardless Fran.
This!
I think this car should focus on I-4s and V6s, with the possible exception for the LS4 drivetrain. If you want to get the younger crowd interested, you should focus on the stuff they're already used to like K20s, 4G63s, VQ35/37s, etc.
