I could get a bugeye WRX for my budget no probs, but then id have the high insurance, petrol consumption to go with it, & the temptation would always be there to mod it & then break it.
Having looked at the stats for the range there doesnt seem to be much between the 318 & 320 at all really. 323 looks good, still a little poke 171bhp & 0-60 in 7.6 for when its required! 325, 328, 330 etc all going to drink the petrol!!
