This event is completely SOLD OUT.

Air-Cooled Affair 004 is a special limited-capacity event focused on pre-1999 Porsches. In typical BCR fashion, there’s an 80/20 split for this event: lineup will be comprised of (at least) 80% air-cooled Porches, and (up to) 20% interesting pre-1999 “air-cooled adjacent” makes/models.*

On Saturday, October 22nd, we’ll meet at an undisclosed location (all-new for ACA004) in Sonoma, California at 7:30 am for some coffee & pastries. At 9am, we’ll take off in 3 groups (HARE, TORTOISE, and SNAIL groups) 5 minutes apart, for a bracing drive on some of the area’s best roads. We’ll be done around noon, touching down somewhere in Marin County, where you’re free to grab lunch, hang out, or just head on home.

Registration for this event is $60. What does your $60 get you? Only this: a rally decal, parking window cling, and an unforgettable day on Sonoma and Marin County backroads with a group of like-minded drivers.

*Examples of “air-cooled-adjacent” cars: non-Porsche air-cooled cars (Corvair, VW Beetle, etc), pre-’99 water-cooled Porsche, Triumph TR6, Datsun 240z, Alfa GT, Lotus Elan, classic Mini, BMW 2002, etc. No post- ’98 cars will be admitted.

Additional info:

The registration fee for this event is $60 per vehicle. Once your application is accepted by BCR, there are no refunds; before you click “Purchase Ticket," triple-check that you are available on the date in question and that your car is in working mechanical order for the drive.

Co-drivers welcome: fill out appropriate section of registration form.

Please give the surrounding shops your business and tip well- let’s not be freeloaders.

Don’t make us say “no burnouts.” You’re better than that, right?

BCR has a strict “No Suitcasing” policy: this is a drive, not a marketing opportunity. Leave your logos, leaflets, FOR SALE signs, stickers, business cards, flyers, and branded trinkets at home.

The drive begins staging at 9am and will take a max of 3 hrs. Drive at a speed comfortable to you, taking into consideration weather and road conditions, always yield to quicker vehicles, and never pass on a double yellow line.

A link to download turn-by-turn directions will be sent a week before the drive. Read them. Learn them. Know them. Live them. Don’t rely on the person in front of you to know where they’re going- they don’t.

Roads are pretty smooth the whole way; usual bumps and such, nothing major.

Gas up prior to arriving at the starting location; limited gas stations along the route.

Cell reception unavailable in some areas.

People live and work in these areas we drive through. Be courteous to business owners, employees, homeowners, ranchers, cyclists, pedestrians, pets and livestock you encounter- let’s keep BCR welcome in the area.
