Too be honest forget about both the 90TSI and the 77TDI .... I recently helped my boss pick a runaround ... he was set on the 90TSI DSG + Comfortpack ...
After driving it he was happy .... the big thing though was a 118TSI DSG (with comfort pack standard) was only $2K more driveaway .... so he went for that instead.
for only $2K I'd recommend you go for the 118. Financing that extra $2K will cost you less than $30 a month extra ..... well worth it IMO.
