In current production cars, I think you would be hard pressed to find a non ABS car. If the car does not have ABS, a simple electronic pickup in the final drive will very adequate.

I just turned in a leased Pontiac G6 (2007 model year) earlier this year that did not have ABS. It wasn’t the bottom-tier “value edition” either, it was the base model with the v6 engine package (which added several thousand dollars worth of options, but not ABS).

then like he said, there’s a pickup and a tone wheel in the final drive. there’s still no speedometer cable.
