A new ecu including raised boost + exhaust makes the base 118d model nearly as powerful as the more expensive 120d!
Combine the same parts with the 120d, and you can go hunting Seat Ibiza Tdi 160s!

This demo car has all the usual stuff: bodykit, larger exhaust & wheels, suspension kit with sway bars & alloy strut brace, carbon-alloy interior parts. Nice stuff. I bet the One will follow the Three as a car with a huge aftermarket support.

Front looks better than the factory "Aerokit", but still I've yet to see a 1-series bodykit that I'd actually buy myself.
