I had looked at ST's when i was looking at my Type R (bought 3 weeks ago) as they were really the only 2 cars that were sticking out to replace my BMW with, the ones i wanted were just out of reach on my budget, or if they were in budget they had the tacky/gaudy cloth seats, i much preferred the leather Recaro's to the cloth on the ST, the CTR interior is a much nicer place to be IMO, really slick shifting in the box, The CTR has better fuel consumption and ST is a bit nose heavy with that Volvo T5 lump in it, any of the R32's and GTI's i seen when looking around were also out of budget or had higher mileage on them than i wanted(100k+)
Suppose it depends on what you like, i also ride motorcycles so quite like a revvy engine, have also had a few petrol turbo cars as well so understand the appeal of both, best thing is to get a test drive of each and make your mind up from there, also check for signs of accident damage as 3 of the ctr's i looked at all had signs of repair work, and not to a high standard either.
