i will drive my crossfire to its death, so i'm not worried about resale value. this is the first car that i'm actually planning on keeping for a while. usually, i go through a car a year.
not too many sport cars hold their value all that well. the g35 is the exception, by far, in my opinion.
if your really concerned about resale value, pick up civic- you can't lose, but you will definitely snooze, somewhat.
