Watching the onboard footage of this classic 2.7-liter 911 at a foggy Laguna Seca brings out a few nervous goosebumps. With every car worth outrageous amounts of money, the track damp and the visibility poor, it could very easily become an expensive pileup. Add to the fact that the competition is wildly faster than this car, and the differences in speed could lead to a collision.

It’s remarkable how quintessentially turbocharged the 935s appear. First, the widebodied Porsches hiss, whistle, and lag out of the corner. One Mississippi, two Mississippi, a little twitch from the rear end, and the beasts quickly become a speck on the horizon. But with the elements making the already difficult-to-spot apexes harder to view, the 935s tend to collect at the corner entry, and the nimble 911 gets to nip at their heels once again.

This happens most obviously at turns 6 and 7, both of which involve blind crests. Who’s going to charge the corner in the fog? This is supposed to be a relaxed Rennsport Reunion, after all.

But the 935 isn’t the only vintage beauty this machine goes up against, and some drivers seem to be racing for big bucks. Classic RSRs fill the ranks, and one well-driven RSR shows that the track isn’t just about power. Chasing the 935 down into the daunting, downhill turn 9, the RSR — a car with only 300 horsepower — gains enough momentum to pass around the outside in the off-camber turn 10. Though Laguna is known as a power track, the challenging downhill section from the Corkscrew to the beginning of the front straight requires courage, skill, some clever car positioning, and an urge to upset the owners of faster cars.
