Mine may not be as cool as a new Viper, but I'm looking to get into a 13-14 GT, or 08+ C6 this coming summer/fall. Good luck on the GTS!
Narrowed the list down to these...but the more I think about it the more I am thinking of taking the turbo off the list
F type coupe R
GTR nismo
R8 5.2
Maserati GT
Aston martin vantage
C63 black series
991 turbo
My current DD is a 99 civic, and while it's in great condition, it's still a 99 civic. I test drove a 2014 Fiesta ST, and I could see myself picking one up in a year. It felt great and those Recaros were so damn comfy.
I thought these were only sold in Europe...i'm guessing they're fun to drive.
991 Turbo is just too expensive for me, with high options they now approach 200k. When I can step into a Metzger 997 Turbo for 65k it's hard to sell me those new ones.
Maserati scares me, love them, but I keep hearing about Ferrari level maintenence.
The others on your list would be worth it I think.
