Capri prices vary heaps (so does the quality of cars offered for sale).
I personally think properly restored cars (if done correctly) are worth a bit more than $25k, but that only my opinion.
I know of a couple of nice restored cars which have sold for more than $25k, but they weren't advertised, as they sold via word of mouth so hence no sales history.
When I went to insure my Capri I didn't have any hassles obtaining a agreed value considerable more than $25k.
But thats only my 2 cents worth.
