My Jeep is my only vehilce. The only time I regret that is when someone hits my Jeep (twice in 3 years) and I have to suffer with a car while the Jeep is in the shop. I was thinking of getting a second Jeep for when my current one is in the shop. That way, when I'm 'finish' modding this one (like that'll ever happen) I'll have another to start on!
My job and house are 5 miles apart. I found that I spend less money on gas a year than someone with a Cobalt, because of the distance we live from work.
