A lot depends on the colour of your Rover or MG. Certain car/wheel colour combinations really suit our cars. My refurbish colour preference is for Brilliant White.
Obviously factory silver always suits these cars as it closely resembles the natural colour of alloy. This is my red ZT-T with OE Gridspokes. Closer view of those wheels show them in pretty poor cosmetic condition. They have since been refurbished :~
Same with these OE silver on my other ZT-T :~
This is what those Gridspokes looked like close up. That's not dirt, just very corroded and tatty :~
... and what they looked like after professional refurbishment.
... and on the car with tyres refitted. :~
Brilliant White :~
Here is that Blue car with refurbished Gridspokes in Brilliant White. They are much admired and I think they suit it admirably:~
Rather than have a wheel less car, I bought a set of inexpensive 18" alloys off one of the members here and used them whilst the originals were refurbished. Usable sets of wheels with legal tyres are often dirt cheap on ebay too. I got a set off ebay from a local farmer for £30. Over the past five years, I have had about ten sets of Rover and MG Alloy wheels refurbished @ £20 ... All my own family's and friends' cars. Yes, just twenty quid each.
I take the bare alloy wheel as that keeps cost down. No tyres, balance weights and Rubber valves removed. Usually get two sets done at the same time to reduce travel costs to-from B'Ham-Glos.
My son recently had a set of five MG Metro 1300 "Pepper Pot" style Alloy Wheels refurbished for the same price. They were by far the worst condition ( corrosion not damage ) Alloy Wheels we've ever seen. The five came back good as new. I bought a new MG Metro back in 1983 and I do not think my memory is playing tricks when I say those MG Metro alloy Wheels came back better than new. complete with protective clingfilm on the actual rim circumference.
The last set of Gridspokes I had done were these. Expensively refurbished to a high standard in a colour I do not like in previous ownership. There was considerable kerbing scuffs on all the wheels. Used an angle grinder to clean those up prior to getting them done. :~
Finally, this is the outfit who have refurbished all those wheels. Those are the pepper pots in the botom left of the picture. I post this image to illustrate the range of colour choices... which is vast. The company City Powder Coaters in Digbeth Birmingham. I have no connection with them except as a satisfied customer.
