Such decrepitude on a fairly new car: such things one more commonly associates with the mundane marques.
This is a BMW 1-series. It’s the E-81 (etc) from 2004.
Very much built to a price, the cost-cutting shows in details like the perishing window rubber. As BMW has lowered itself into the cheaper end of the price spectrum such things can only be inevitable. Next I’ll try to find a Mercedes similarly afflicted.
