gt5p has a good selection of cars but the customization is nothing compared to grid. By no means is it bad, just nowhere near as good.
The 6 tracks can be be played in forward and reverse so you can count it as 6 or 12.
There is plenty of variation in style of racing ranging from; championships, time trials, overtaking, car/ manufacturer and power specifis races, drift challanges and a few more.
Online play is good fun and it had all sorts of scoring and leagues.
As an extra it also has gt:tv where you can download and watch programmes about cars such as top gear and many many more.
I think it's worth it. It's almost like a full game at half price. If you like driving sims, you cannot go wrong.
