Hi All, I'm serioulsy thinking of getting an A3 Sportback TDI 170 Sport. Clearly will have to have a good test drive, but I was wondering if it is worth the additional £900 over the 140. I previously had an '04 3dr 2.0 TDI Sport, which was pretty good but not spectacular. Obvioulsy the diesel engines have moved on quite a bit in the last few years, but any views would be really welcome. Also, would the 1.8 TFSI petrol be a decent alternative? Thanks in advance.
