Do you know by any chance if its required to pass emissions in Detroit. I am just curios.
I know in Denver, CO, emissions are pretty tough. Almost like in CA. But out side of Metro Denver, no emissions requires.
There was a guy here in Denver, that was selling 2002 M5 with supercharger, tuned to 500HP to the wheels. He sold his car for only $19K, all because it wouldn't pass emissions. I think car had only 50K mile (its been about a year, so I don't remember the exact mileage).
Someone got a sweet deal.
