Nice choice!@Dino D - Just bought a montreal blue Z3 and if she shines up anything like your car i will be ecstatic.
We know it’s the best blue blue but we’ll let the kids play..
Mines has fresh paint so I’ve not polished, just waxed
But even before the paint job, with a good polish and wax the colour responds well.
This was just hand polish and wax, in the pics it looks good, close up course it showed it age and mileage over 100k but the paint still was good, no fading etc.
A good set of wheels really lifts it too.
