You know, if you have the room, you could get yourself either the CTS-V or ATS-V as your summer daily driver, then in the winter, buy yourself a beater to get you through those three months. After every winter comes tax return season and people have money they're looking to burn, so you can easily sell your car on Craigslist for just as much if not more than what you paid for it.
Sigh. If I had my way I would get an ATS-V and an early 90s Bronco to mess around with. The downside of the V to me (besides that I'm not sure I want to sink that much money into a car) is that the designer of its exterior is a former boyfriend of my wife. Silly as it may be, I find that kind of emasculating. Not a normal situation for one to have to consider when purchasing a car.
You know, if you want something similar to the RX-7, The Scion FR-S/Subaru BRZ is actually a well put together car. You'll hear people gripe about their lack of power, but they're missing the bigger picture of amazing handling. They're nothing like the FR-S or the RX-7, but the Ford Focus and Fiesta STs are great cars in their own right. If power is your thing though, and you still want something that's a bit more practical price wise, the new Mustang is hard to beat. Though, I'd probably wait until the 2016 or 2017 model year comes out, so Ford has a chance to work out the first model year kinks.
I like the Mustang, and I'm Ford employee discount eligible, so it's crossed my mind, but I'm just not into muscle cars. The Camaro that's coming out next year is cool, too, but doesn't appeal to me for the same reason. When it comes to fast cars, I'm more a sport coupe enthusiast (ATS-V, M4, RS5, etc). As it stands, I'll only buy a Ford or GM, because I can get discounts on either (not because of any buy American ethos). Currently I drive a Silverado, and there's a strong possibility I'll just end up getting another one, but goddam is it annoying when faced with a small parking lot.
You know, each generation that Mustang becomes a bit sportier, especially this generation now that it has an independent rear suspension. You got a bit of a pricier taste in cars though. Pricier, but still tasteful. Besides the parking, how do you like your Silverado?
