my new car i have no regrets and i plan to keep it that way. my old car, good Lord are there lots.
i really regrett shoping at the local speed shop. i went in wanted either progress or h&r full coilovers and the owner talked me into geting some arospeed units he had there for 5 bills. man i wanted to rip them out and beat him with them after i drove hte car the first time. i sold them shortly there after for 360 installed.
i only use this shop if i need something that i can't get easily online or somewhere else

i really regret doing a body mod to my car. man i kick myself daily for letting that "body shop" touch my car. not only did the job not get finished but he butchered my car to the point that i sold it rather than look at it. i did undo his mess but it still brought back the memeories when i looked at it.
i could type up a huge list but that's the worst stuff for me. i learned my lesson
