I've an auto legacy twin turbo. Was a bit hesitant about buying it simply because it's auto, my god its easy driving lol.
I'd honestly say they are really not what you'd expect, also have the sport shift option as said and gives you the manual feel when you want it. I get great mileage out of this, literally no worse than a 1.8 SRI vectra petrol I had previous, which was averaging about 35mpg.... I know, crazy? Driving around towns and stuff it's a bit heavier alright but that's in every car.
If you drive easy it shifts up the first instance it can so you end up shifting to 2nd gear at like 2k rpm, rather than a manual where you tend to shift at about 4k rpm. Makes a difference, id say you'll have to get a drive in one, a good drive. At first it's just a bit weird lol
Viewed mine twice before I bought.
