I'll give you an answer based on you buying a Subaru - because this is a WRX forum, as you said.

There isn't many deals to be had atm. I just signed for a MY11 WRX from Subaru OP and I am a repeat customer of them and they also know I am a regular on this forum and have a big mouth, and even they couldn't give me much of a deal on the MY11. There is no stock atm coming in - so you may have to pay close to RRP for one.

I'd go the grey, just coz it looks classy.
