I'm 29 and I still "pimp" my rides I guess you can call it that.I put in or supe up tbe drivetrains,rims,dvd,navigation,all the usual stuff but I like muscle cars or hot rods.my favorite cars of all times are any of the ford fox body platforms but especially the mustangs.I say if you get to a point you don't want to trick them out anymore you aren't a true car guy.its in your blood.I tweek or mod everything.
