wow.... lol my civic is like brand-new as far as mileage... 14 years after my car came out of Ohio's plant, it still only has 97,761 miles (and yes, I just looked at the odo to get that number lol)... 142k isn't bad at all. It's a Honda... 100k+ is still only getting the car broken in. I say go for it with the mods... where do you live? I have a body kit I could sell ya pretty cheap (R34 front bumper, Black Widow I sides & rear).
