I was also going to ask how much of that you could put towards your mortgage. Also, it seems as though you are buying used, which I think is smart. Even if your interest rate on investments was better than the rate on the car loan, you lose a ton of value in initial depreciation.
I was in a similar situation as you recently and was looking at the exact cars you were. I decided on a Gen V Viper. I live in South Florida and I see multiple Corvettes (literally a new Z06 somewhere almost every day) and 911s, but never Vipers. The Gen Vs are actually really nice cars inside and don't have the traditional Viper quirks (or at least at a much lesser level). They are awesome performers and you can't go anywhere without someone holding their phone out, taking photos or giving the thumbs up. They are also probably the cheapest "exotic" to maintain.
