We could just start with the specs, because those big numbers just keep on getting bigger. For example, GT3 had around 160 cars to choose from, but Gran Turismo 4 makes that look puny with around 700 different models from just about every major manufacturer, the only big exceptions being Ferrari and Porsche. That figure includes a host of new and current models, some superb 1980’s and 1990’s models (available second-hand for the budget-conscious novice), a wide range of classics and some great concept cars. This alone should make GT4 irresistible to the leather-jacketed goons who line up for a place in the Top Gear audience, but it’s worryingly good news for the less car-crazy gamer too.
