I am looking for replacements because like yours they are going white under the clear covering layer. I had a look on eBay and they seem to be around £20 a set. Although I am searching for ones for the Ampera there is still the caveat that you need to check the diameter of the clips. I had thought of just trying to get chrome & black coloured badges/stickers and either try to fit them to the existing ones or have a go at printing some caps too in plain black with a flat face.
Looks like I need to print some. They'll be black, flat ended, and to make removal easier I'd put a circular hole through the middle, made of a donut shape removed from the plastic. You'll see 5 small holes in the face, to line up with the spokes, and these will all meet up inside. So you can poke some wire through to remove.
I bought a set from Lookers on eBay - they cost approx. £30. Lookers were selling off a load of Ampera spares earlier this year - I also picked up a spare reflector for the boot lid and a new rubber extension piece that fits under the front bumper.
Have owned my Ampera for 3 months now, and love it. Handed back my company car and am now saving money!! especially tax.
Have used the posts to:
Fix steering lock fault whilst stranded
Change headlights lamps, so can actually see where I am going in the dark now.
After 105,000 miles, my cabin heater isn't working when in electric mode. The reservoirs are all topped up... and the heater works in petrol mode. A mechanic used his diagnostics and found no faults. Though he did nothing to the car, the heat returned in electric mode. Hey hey! But twenty...
Having never seen another Ampera around me here in Horndean since I got mine last October, my daughter just texted me to say she has seen a white Ampera in waterlooville just now, with reg number starting YP62 .. Is this one of you chaps? :-)
