I'll go on record saying that's false. Having bought 2 new fords in the last year, one being my focus st3, prices vary GREATLY by even driving across Ohio. Not saying not to buy from Fiji, he's a great guy, but definitely shop around. Just an fyi the dealer I got my car from has a 2015 st3 loaded for a hair over 27k on their website. Having not done any research I'm not sure if that's a good price but my 2014 st3 was a few grand cheaper back in January 2014 when I bought it.
