I went last night. Overall, it was on par with previous Philly shows.
Some highlights:
1. Bewbies. Nissan, Honda, Toyota, and Porsche were the best
2. Camaro concept
3. STi and Legacy GT wagon road race cars
4. 911 Turbo and GT3 (turbo was locked, GT3 on a stand)
5. New Malibu (can't believe I am saying this)
6. New Lancer (on a stand)
7. New Minis (all unlocked)
8. Z06 (unlocked)
9. The exotic car guys will let you sit in an exotic if you ask really nicely
10. The Forester with STi bits in the Tuna Saloon (aka Tuner Salon)
11. Audi R8 (on a stand)
