Choosing a Car

I have been debating with myself for a couple months now on what type of car to buy. There are so many different makers and models to choose from. I would definitley love to have a car with some horse power, at least 300hp. I like the Pontiac G8, but the fact that it's a pontiac is what bothers me. I am not too big on pontiac made cars. I do love Chevoralet made cars. I want to buy the Chevy Impala but it can't just be a regular standard Impala, it has to be the "Impala SS" and no other kind. I also want a Tahoe. I love that suv. I wish I was rich so I could buy all the cars that I want and that would solve all of my problems when it comes to choosing the types of cars that I want.
