Finally have time to sit down and play some GT5 again. Have been out since a few months but going to patch up tomorrow and connect the PS3 again to the HD screen
Good luck with that Bram. If you've been out for a few months then there will be a host of singleplayer content for you to get through in the form of seasonal events. They're generally not that hard to win but are good for building up cash in order to buy your favourite cars. (As predicted, the bonus cash/XP has gone on... and on... and on...)
As for online racing, you'll likely run into the same connection/performance issues that have all but killed club racing. I have slight hope that the maintenance over the next four weeks will resolve the problem, but I'm not holding my breath.
Ill stick to offline for now. I remember I was stuck in my carreer mode when I ran out of cash after a bit too much tuning Now I want to find the car ill be buying in real life (Volvo C30) and test it a bit
