1976 Aston Martin Lagonda
The ultimate hacker's car.
This was an exotic hybrid of sport and luxury, totally electronically-controlled by state-of-the-art-at-that-time digital technology., including an all-electronic dashboard display.
Unfortunately, the state-of-the-art of digital technology wasn't terribly advanced in the mid-late '70s, so most of these cars still on the road are plagued with electronics issues.
It would be cool though, to get one of these cars and mod the fuck out of it. I'd like to hack it to run off a Linux PC, replace its original LED instrument panel with a TFT LCD display and add GPS, EVDO cellular Internet access, HD-DVD playing capability with backseat passenger displays, rear video camera for parallel parking, etc.
