Most of the 15th AE cars fall slightly under the recommended PP for eligible races. For instance, the GT86 comes in at 446PP. The dealership model(s) are 406 and 407PP if I remember off the top of my head. Coincidentally, 446PP gives you quite a race in the 500PP events for which it is eligible(if you're an average driver like me). The 15th AE was no extra charge at Gamestop(in the US) so I went for it. I'm close to completing IB race events and I've only needed to purchase the Kart 100, Kart 125, Prius G '09, Toyota GT86. Yes, you bet your next meal I use these cars. I've won all the gift cars up to this point but, wow, some of the cars I'm hearing I'll need later on...Well, let's just say I'm glad I caved on the 15th AE edition. I've earned approx. 2,000,000 CR and still no need to spend money except for tuning the Acura NSX '91(which drives like a dream).
