What car should I get?

[Andrew]

Well i'm 18 and have been debating if I should get a car or not, I finally decided that I should get one. Now the question is which car? I have a few in my mind, A dream car of mine for a while as been as Mercedes S550, But now the technology in cars are amazing and the only way I was going to get the S550 is if I bought it used. Now that i'm thinking about it I was thinking that it's too small of a car for me, that maybe a SUV would be applicable. Here are the options really, 2007-2008 Mercedes S550 4Matic, Fully loaded with Night Vision and all that. The new 2011 Jaguar XJL RWD fully loaded (Not even comparable to the S550 options). 2007-2008 Cadillac Escalade AWD Fully Loaded (Except Power Folding Running Boards). I'm really all for Technology and the new 2011 S550 is the only car that can offer but I just can't afford a 120K+ Vehicle, Don't matter how good the options are. The S550 and Escalade will run me about $40K-$45k, The Jaguar, I can barely afford and whill run me around $65K. I've loved the S550 for years and have always wanted to own Mercedes Flagship Sedan but I don't want to look cheap driving a old S550 espically since you can tell a difference now. The Mercedes wont feel the same too me since I know that the new 2011 model's have options like Blind Spot Assist, Lane Departure Warning, Sleep Warning, and all that new stuff.
