Thanks guys! I was thinking of changing the wheel centers to black or blank ones but the colours in the current ones seem to match the rest of the car quite well.
Driveshafts, coolant & front calipers now need attention so I can get closer to the elusive RWC & MBCV registration. Damn shame I can't use any custom plates on the car but maybe one day soon VicRoads will change the regulations... In the meantime I'll just leave one on the parcel shelf!
