Apparently this Z is FIA classified as a Touring Car, different to the two seater. So I'm wondering if anyone has raced one, road course, and if so how it compares with the two seater.

With the longer wheelbase I'd assume it would be a bit more stable but, if so, I'm not sure how this would translate into handling characteristics. Perhaps this would be a disadvantage in tight turns but an advantage in long fast turns.

In Belgium, the Miroux have raced at the 24H of Spa with a 2+2 in the 70'

Not worse thant a Capri

Better aerodynamics, more weight. Slightly slower acceleration, better top speed.
