When shopping for a second-hand 911, a used and abused track rat might not be at the top of your list. Here's Magnus Walker to explain why you're wrong.

You know Walker. He's the apparel baron turned Porsche aficionado who's out to own every original 911 ('64-73) he can, and the list of his stable is as long as his dreads. But this latest addition isn't Walker's normal fare.

When people ask him what's a good starting point for a lifelong 911 obsession, Walker normally suggests an SC. It's got the right combination of performance and price. But he didn't own one, so he decided to take some of his own advice.

He picked up a 1978 SCHR, a former track car that had the right kit, lots of documentation, didn't require an exorbitant amount of cash to get road-worthy, and took about six weeks to build. The SCs may be one of the last air-cooleds mere mortals might be able to afford, and Walker makes a compelling case for buying a track car, with a bit of help from the eGarage crew.
