Compared to the 1602, the 1502 had less equipment, like a missing rear anti roll bar ,no rotatable vent windows and no chrome strips. The 1600 cc engine is fully rebuild with forged pistons and is nice to drive. 80mph in 3rd gear can be done easily. This 1502 feels to have much more power than specified from the factory.
In general this BMW is nice to drive with the brilliant working gearbox, makes no noises and has a very good working heating.
