I ticked the box for Auto Insignia diesel when I hired in the Uk. Instead I got a 2litre diesel (bluemotion) 177bhp? Passat.
Apart from no cruise I could not fault it. Fast, always in right gear either five or six in total can't remember, great in traffic and despite being ragged a lot, returned over 60mpg (3 weeks approx 4000miles). If they do one in a Golf it would be very high up my list. I think it even had aselectable option that in effect provides engine braking but not sure.
I am perhaps a lone voice but all cars ought(for years) to be autos and if diesels are more economic than petrols- then diesels. Manual an option only. Lets be honest, there aren't many places south of Leeds in England where you can use a manual to good effect. Wales, Scotland now that is different assuming no speed cameras.
200 miles a day , six days a week that advertised car has done. I don't think it would be many short journeys but you never know!
