Think the Polo will be a “harlequin” one? Has it got the teddy bear alloys as well? They always made me smile, like someone said “sod it, we can make the wheels any bloody shape we like and I am bored of propellers and spikes and all that rubbish, here is one for my kids :-)”.
Oh, and if they make a goodwill gesture that you are happy with, take it. If they don’t, don’t take it.
I am always a bit peeved when there is an expectation of compensation as though it is some sort of income stream “oh look, someone made a mistake, I should profit from that then”. Disappointing I am sure if you have waited a couple of months, but who knows, they might have the correct coloured clip on dash (if they offer loads of colours, it might be that easy) in the post already, and you only have to wait a few days… no real problem.
Another two months, we will ring when it’s ready, more of an issue…
