Worth every penny and more.
Either throw around £500-1000 at it re-commissioning it, and you basically have a brand new Nova on the road. Can you get a new car for under £3k? No.
Or tuck it away as a collectors item: it certainly won't go down in value.
Or would make a cracking base for a non sunroof rally or show car. Think along the lines of how much a brand new shell would cost?
Once Novas go historic rallying (in a couple of years), prices for shells and works bits are gonna skyrocket. You heard it here first
. So get it bought while it's cheap.
It will sell.
