I have both the Le Mans quattro and the Nuvolari quattro from prizes, but have not fixed up either. Their power and weight details are very similar so I was wondering if their performance was much different when tuned. I think it would be more fun to tune the Nuvolari since I like the looks and it I guess it would be more rare racing online, but I don't want to dump money into it if it is slower than the Le Mans. Hopefully a tuner will help out here.
