Have thought about buying a cheap CLS55 and running that as its a bit less racy but why should I have to.
I've always been concerned about where I park but I don't let it overrule my choice of car.
I'm too stubborn...
I would continue as is and see what happens. You may find you just had a bad run of idiots and the situation resolves itself.
Saying that, buying a CLS55 is not a bad idea! Bit more class and grown-up than a C63 IMO.
