Yep it does look like a genuine WRX300 model from what I can see with the STI spoiler been added on after, can't tell if it's a genuine STI spoiler or not from the pictures. Some people try to pass these off as UK300 I think thats where the confusion comes in they was only Bugeyes yes it should be 265bhp from the brochure ;)

Only thing I don't like the look of is that someone has put AWD badge on looks out of place :D
