i'm looking at egay at 450's and i see some are blue and some are red and some are dark colored ( not red) dose this mean the diferent type of car it came out of? like 1g or 2g dsm? kinda lost on knwoing these i don't want to pay for 450's and get 390's.

 

so red is 3erd gen? and there all 450's just diff colors.. ok cool thanks
