Too big? It's replacing the Neon... think a wagon version of a Neon - atleat in terms of size. I would think it is almost exactly the same size as the Nomad. Also don't forget that they are goign to make an SRT4 variant of it eventually.... so that wagon will be fastAr than light and time itself.
Also the Solstice and Sky are actually a little bigger than the Miata - that is one reason why they are soo much heavier.
