It is a shame they have lost the racing heritage. The MG Maestro Turbo, and montego, the MGV GT and the like, it has a rich racing heritage. Now it's just another youth oriented car brand! Perhaps one day we'll get a proper MG again.
I think brake wipe is where the brakes touch on lightly every now and then when it's raining to keep them water free. Some VAG group cars have this. It has been blamed for pad wear but I think that is unfair. A good driver would do this automatically when wet just before needing to brake, and when driving through puddles.
