Newbie looking for first subaru

[Clyde]

Hi folks

my wife and I were looking to change our Audi A3 due to my wifes recent neck/back surgery,we came across Subaru by accident, intending to view the Mitsubishi asx, but sales guy said not to overlook the Xv.we were initially pleased with spec of the new face lift model but couldn't believe the diesel doesn't come with an automatic, but usual sales were pushing the petrol insisting we could still get 45mpg with a 2 litre.is this just the figures from the brochure he's quoting with real life being nearer he 30mpg.
