Hello everyone!
Recently, I have been looking to buy my "real" first car, with my own money
I am a current high school student, and I have saved up a reasonable amount of money to purchase a car from working, etc.
I am dead set on a purchasing Mercedes, but I don't know which one to get! I currently drive an older Jag XKR. A major issue I have is my height- I am 6'3 so headroom may be an issue.

Here are my thoughts so far:

C Class- Very nice car, but it's too small
E Class- Clean looking, but lackluster for a younger person, in my opinion
S Class- Elegant, but too big for my needs. The S600 is very nice
CLK Class- Very nice, but not the most sporty looking coupe
SLK Class- Too small
CL Class- Expensive, older models look "cheap?"
SL Class- Very nice, but it's not practical for a high school student
ML Class- We had one several years ago, too many electric gremlins
GL Class- Too big
GLK Class- Good size, but expensive since it's relatively new
G Class- One of my favorites, but the size and part availability isn't practical for me
SLR- I wish xD
Chrysler Crossfire- It's a nice little car but too tight

What do you guys think? What should I get? I'm stuck, I can't decide!


Thank you very much for your advice!
