The sportback in red looks nice... or even the denmin blue looks good...
in regards to engines..
the 2.0TDI is 140BHP... the 1.9TDI used to be 130BHP but has been detunned to 105BHP so its not too close on power to the 140.... (as the 140 costs a biot more..)
i would get to your local audi garage and test drive a 1.9tdi... tell them you are wanting to buy one etc etc... to get a test drive and then tell them you need to think about it.....
going back to colours.... go to
Audi UK > Home and chose model and you can look at each car in different colours.... or even just go to your local Audi garage and look at all the colours there..
Cheers
