Hot rod mode makes this a buy.
Little things; hot rod car looks a tiny bit too long, and it looks like the car just plugs into the trailer for rodimus car mode. But that's ok with the off-sets of two heads and it being that many modes in one.
They could have made two differnt toys and tweaked them up a bit more to suit each character, but in a way it's good to have it both in one as it's just one purchase then. I'm sure people will buy two to have both at the same time, but to me they never existed at the same time, so it's a good acknowledgement from tak-tom on that.
Can't wait to see MP Galvatron.
