I just placed my order last week. The car that I ordered he said could take up to 12 weeks, but he said he would try his best to find a car that matched exactly what i wanted within 300 miles, there was one closer that he could get but it had extra accessories...blahblahblah. I told him to just order me one or find exact what I want and he said he'd be in touch.
After reading other posts on the site, it seems like 90 days would probably be the longest it would take. Quickest being 5-6 weeks, with the occasional ones coming quicker under certain circumstances.
And the gauges don't differ at all between trims. They're different on the STI's though.
