Superb mod.
These 1979 vehicles looks and sound super authentic. The drivers visible and animated arms on the steering wheel, in the cockpit view, make this mod that more realistic looking. The gauges in the cockpit look authentic and the drivers position also seems just right.
These vehicles, with traction control and stability control set to max, are driveable on the keyboard.
The driving physics seem just right. The cars aren't too bouncy -for the better and worse- and drive very predictably and straight.
These vehicles aren't quite as difficult to drive -for the better or worse- as my '82 mod (which does make the cars, in a sense, funner but more challenging to drive) but also don't corner quite as well, nor are quite as fast as my '82 mod.
