So I currently own a Ford Focus 1.8TDCi and I am going to upgrade it, Now I want a German car but my first choice is an Audi A3, but I think I am being too fussy.

•  140BHP or 170BHP
• 2.0L 
• The Less road tax the better but trying to keep it less than £130
• I want Steering Wheel Controls for my Music
• S-Line would be nice but its not a must
• 5 Doors ideally
• Diesel
• Manual
• No older than 2008

So what sort of model am I looking for? (I have £6000 (max)

An SE should float your boat:

S Lines are available in your budget but likely to be very high mileage. Can always get the 140bhp remapped too.
