sti's are a quick car and are good value for money but you guys miss out on some real bang for buck cars.
Over here ford make a large passenger sedan called the falcon. The falcon bears many preformance models but the best is the FPV F6.
4.0 straight six turbocharged. ZF Six speed Auto. Brembo Brakes.
Pwr 418 bhp, Torque 565 Nm. 0-100hph 4.79 seconds. It accelerates from 80-120kph faster the a 911 turbo. Has a 5 star safety rating, amd gets 23 miles to the gallon. All for $65,000AUD or about 28,000GBP.
Over here a STI costs about the same, but the FPV's and HSV's rule the roads.

If Ford Aus exported these to the UK i'm sure they would be a hit.
