I saw this list posted somewhere else too, but there are some Shelbys:
Shelby Cobra 427 ‘67
Shelby Cobra Daytona Coupe Race Car ‘64
Shelby Mustang GT 500 KR ‘68
Shelby Mustang GT350
Shelby Series 1 ‘98
Course they do not list the year... but either way... I can not wait for this game. Winter is going to take too long getting here.
