My previous car before the GTI was a new ST-2. I have to say it was pretty decent package for the money (£15,500) Although I went for a nice discreet colour (black) The engine makes some cracking sounds and you feel the punch of the engine more than in my current std GTI, particularly that extra torque.
Chassis wise it felt more like my std MK 4 Anni - bit 'wallowy and lardy' in the faster bends, more of a big GT than a proper GTI, and does not come close to the std handling of my current GTI.
Had a few rattles here and there which were annoying in a brand new car, (particularly rattling Recaro seats and creaking door seals!) eventually put me off hence the change back to the VAG fold.
I guess overall the Focus has great power and a decent looking interior in St-3 guise, but the downsides are a few rattles here and there, and poor mpg.
Rattles can be fixed, but depreciation cannot!
