A bit late to the Maserati portion of the car list discussion, but I find it completely bizarre that none of the Forza games, and almost no racing games, period, include any of the cars manufactured between the Tipo 61 (1961) and the AM336 Ghibli Cup (1997). That's an entire pantheon of classic sports cars and GTs -- the AM115 Ghibli, the Sebring, the Bora, the Merak, the Indy, the Khamsin, the Kyalami, the Mexico, hell, I'd even take a Biturbo at this point. It's like every racing game decided that Maserati only exists when they're a regular fixture in sports car racing or something.
