Why not consider a grand sport vette as a second car?
Having driven a modded 2011 gt500 a lot, the inability to put the power down was maddening. Plus the solid axle made the car unstable on poor quality roads and broken pavement.
To me, a grand sport would be a better second car. Plus it can also be made really fast for cheap. Neither car has a great interior. The gt500 probably has better tech , but who cares in a second car?
