so i’ve been saving for three years and i just turned 21 and im going to be purchasing a 03 mercedes clk 320 ?

i am soo excited. what does everyone think about this car. im getting a fully loaded one. black. i will tint the windows and put some 18 inch deep dish black rims with a chrome lip. i just ordered the rims on ebay. too flashy for 21? or do you think its good?
no ive been working full time since 18 and purchased a renal house and saved up 19.5 thousand liquid cash. so im going to treat myself to a mercedes because i love cars. im trading in my mustang gt for it.
well if i can handle a 300hp rear wheel drive sports car. im sure i can handle a luxury mercedes thats not as fast.
