OK, so I still can't really afford one :-\ but it is very tempting. The add says it has an Eaton type compressor - what does that mean - is that good or? Will toyota dealer be unhappy you bot it somewhere else or tell you it is not a factory item? Any feedback re superchargers pos or neg is also appreciated. (I have read several threads here but anything new is helpful) Also one for CDan - what does water (or methanol) injecting do? Thanks to all.
