Well, go to www.cosmogames.com and check their prices. I would not bid any higher than what Cosmo has listed for those products. The AE86 has the new steering system where the front wheels turn the car instead of the rears. That may be a little nicer and more like actual driving than the other ones. I have not actually driven one, so that's just my guess. The rear steering does work very well though, I was pleasantly surprized by how it keeps the car very controllable at high speeds. My Char-G's have a tendancy to wipe out when I try and turn at full throttle, the DigiQ just kinda banks a little and keeps right on going. Fun!
