Unfortunately the tie ups between car manufacturers and recommended oils is rarely down to the best choice for the car, it's usually due to which oil company will pay the most. BMW and Ford recommend Castrol, Merc and Porsche recommend Mobil, Ferrari recommend Shell etc etc, but there are plenty of companies that make oils that are just as good or better for those applications. For example, many Ferraris use a 5w-40, so that would be the Shell Helix 5w-40, and while it's a decent oil, it's not one of the best on the market, there are a lot of proper top end performance oils that would be a better choice. A certain newish model from a manufacturer recommended solely using one oil, but that seemed to be linked to engine failures when driven hard. It wasn't proven, so I won't give specifics.
For a 3200GT, for example, we have several 10w-60s that I would happily recommend

Fuchs Pro S, Millers CFS/CFS NT, Red Line and Gulf Competition are all top end 10w-60s that are ester based, giving the best level of protection on the market. The Castrol Edge, Shell Helix, Valvoline VR1 and Mobil 1 are good synthetics too. The Fuchs Supersyn is a more basic oil, but still a good one and good value too.
