They look good in white, whether it's refrigerator white or off white. Red vinyl on the inside looks good with off white, but that's just me and my liking of slightly more eccentric colour combinations again.
I hope your beating those panels and replacing the cancerous metal, not just bogging it, even if it is going to be a daily. It deserves it, the Mk2 really isn't recognised enough, which I suppose is good because it's more unique, not just your ever popular Mk1 or Mk3, or commomn as a house fly Mk4 and 5.
I'd love to resurect another Mk2 as a daily, but I think I'll wait till I've finished my V8 Mk2 first.
