So Brandywine just quoted me $1300 for the sport steering wheel and associated air bag. All that for an option that costs $250 when you order the car.
Really sucks that Porsche listed both the standard and leather sport steering wheel in the Leather options section of the car configurator. I didn't look there at all since I wasn't going to add any leather. I had no idea the option even existed until after I'd taken delivery.
