Almost a year has passed and I finally got it and played it a bit. I start being obsessed about getting as many premium cars in my garage as possible. Even though I rarely drive something else than my current favourite, the Ferrari 458 Italia (of course in red, since it doesn't matter what color a Ferrari is as long as it's red). Also, if GT5 gives an indication of how those supercars behave in real life I will never get a Lamborghini. They are all horrible to drive. And now I have to get a Gallardo just for one of the races...
Talking about getting for the races: how come there are races you need cars for that are almost impossible to get? I didn't find a single pick-up truck yet and would need one for one of the races.
One thing I'm not sure what it's good for is the B-spec mode. It looks like a stripped-down version of those F1 Manager games. The way I can influence the race seem rather limited and my driver is a moron. I gave him a Murcielago in a hot hatchback challenge but instead of just easily going for first place he would continuously ram into the leading VW Golf until I gave the order to overtake. He also has this tendency to spin out of control on a straight, as if a very angry wasp got into his helmet.
Overall I really enjoy the game and look forward to the expert and extreme races.
