The Automatic Box IMHO is a Great unit but is a lot thirstier than your manual one, average about 13% but does drink more on Local Town Runs.
I still average around the 44MPG on mixed driving more on Motorways.
It is a 5 Speed Auto box with a Sports Box Switchable which lets you run revs higher before change up, there is also a Winter Box switchable option which pulls away from 2nd gear and is effective.
You can drive very Spirited believe me.
and with a Ron Box and other Mods GG felt it as quick if not quicker than his MG V6 when he took mine for a spin.
Just make sure Fluid is changed at Correct Mileage and with the RIGHT stuff.
