I recently took delivery of my new 3.7 Roadster. Unfortunately, I missed the boat with regards to an ARP4 order, but there were certain styling elements of the ARP4 that I really liked, so had them included on my car.
Now if there had been an option of a road going ARV6, that's what I would've chosen. I certainly think a 3.7 Roadster appointed like an ARP4 would prove a popular model.
