This is incorrect, the DSG is only available on the 115 SE Tech, you can't have a manual for that engine/spec combo - if you want the 115 with a manual box you will either have to go up or down the range.
Thanks for your comments @me_lee and @Koma.Toes , I followed your advice and overcame feeling cheeky for test driving a car from a local dealer when I'm not buying/leasing from them. Took the car for a drive and really loved it, however my daily commute elapses hilly and sinuous Devon&Cornwall roads and I felt that the car was a little bit needy uphill... nothing major but just enough not to feel comfortable driving it. My local dealer also told me that they'll match this offer, so as soon as I see something slightly more powerful I'll go for it. :)
tumbleweed. Perhaps someone who doesn't understand leasing?
No, that's not quite correct. The manual is available for all engines (from 95 upwards and including the 115) whereas the DSG is only available from 115 upwards. Can't see why anyone would get the 95 when the 115 barely costs any more, gets to 62 1.4 seconds faster and has more torque as well as almost identical emissions and fuel consumption.
There is also the DSG option which I believe is 115bhp rather than the 95bhp engine on the manual version.
