Glad to hear you're a fan of the non-super cars. Personally, I prefer classic muscle and other everyday drivers (Integra is a good example). I look forward to driving some of the higher powered cars in the game. But, in every GT release, it always turns out that my favorite cars are the earlier ones. They've always felt closer to what I experience in my own real life vehicles.
I'm at work as well. I usually get on around 9PM CST give or take depending on what the family is doing. By 10:30 or 11, I'm to the point where I have to go to bed or I'll have a really rough time at work the next day. But, that's usually enough time to get a little GT fix to hold me over until the next night.
