Welcome to Down On The Street, where we admire old vehicles found parked on the streets of the Island That Rust Forgot: Alameda, California. A surviving Datsun 510 is the Bluebird Of Happiness for us!
We saw a 510 wagon not long ago, and there was this 4-door 510 last summer, so let's have a coupe for the complete set. This appears to be an early-70s model, judging from the bumpers, but it's tough to make that call on a car as parts-swap-friendly as the 510.
It's banged up and there's a rollbar and racing seat, so this Datsun appears to be some sort of autocross and/or drift monster. I've been hearing crazy talk about a possible 510-based 24 Hours Of LeMons team coming together in Alameda, though no doubt any two-door 510 would be too valuable for such a project. We'll see.
