In Colorado, if you have ever registered your car and let it laps, when you do go back, they charge you for the full period of time. So if you let it "rest" for 5 years thinking you are saving money, they hit you with all 5 years registration in addition to current year. It can get very expensive.that's too bad. I think if I were him, I may have just kept it anyways and been an outlaw. I mean, even with serious hotrod like that, the percent that he's going to be pulled over is low unless he's racing at stoplights.
but then, i'm not a good judge as i'm an outlaw, my gxp registration is outdue for months but I drive about once a week and do not race and I know from experience that if you just tell the register you haven't driven it; they'll give you the new registration. I figure its really not worth their time over a $60 permit.
