Ok, things move slowly in my w116 world, but I didn't realise it had been almost a year since I first asked about this! My whitewalls (Maxxis MA1s) are apparently 'lost' somewhere in a DPD warehouse, but I have at least finally ordered them, so have made some progress.
That brings me to the next question. I am moving from the colour coded hub caps to a set of bundts that came with the car. These are generally in great condition, but in a moment of unusual foresight, I have decided it would make sense to get them refurbed while they are off the car and without tyres.
I am wondering about the colour of silver to go for. One option is to go with whatever the original colour is, but mine look a sort of grey-silver, and I worry that they will look a bit tired on a silver car. So the other option is to go for a lighter (more modern?) shade of silver. I feel this may 'lift' the slightly bland silver of my car - but keen to hear any experiences/views on the topic!
I've been quoted £245 for four - about US$340. Seems quite pricey, but the place is local with a reasonable rep.
