Blue is another tough color to find. I do see a couple out there but none out west.
I did see a 2003 Seal Gray over Gray interior car with X50, PCCB car show up on eBay today. Private seller. It's a low mile coupe with the RUF "R" 550 upgrade and an Aero Kit.
If it hasn't been abused and is as good as the seller states, it would be a great car for the right price.
I'm close to the car and would be happy to lay eyes on it for anyone interested.
