In my opinion you shouldn't have either one to start off with. With a mustang you are more likely to get tickets and get in a crash. Jeeps are not fast but they roll over very easy. Look for somthing that's good on gas so you have more money in you're pocket.
jeep for sure your less likely to speed and less likely to be pulled over for routine checks a red mustang with a teenage driver ..to patrol officer like a red rag to a bull ... you would not make two blocks lol
