Wow Carl, nice Z I just went to your site. I mainly just do track days and a few time attacks. I autoX mainly, the sentra is currently get a Disco potato put in it. Once it is done it will become more of a track car.
The Granite Sentra is few and far between. It was only available for 2 years. Black and White are both PITA colors to keep clean. Silver is way to common. The red and blue aren't bad, but probably aren't the best for resale, so grey it was. The Pathy will be used as a tow vehicle for my Sentra, and for the RSX I autoX.
