Other than getting into the back seat to do the interior I love working on our MINI.
Two things really stick out for me. First the brakes dust terribly. If you stay on top of it you can keep them clean with wash soap alone (I use
Meg's Gold Class). If you want them clean all the time expect to wash them every two or three days.
Second, due to the aerodynamics of the car the rear collects a lot of dust and grit.
PC.
