I had a loan Q2 30 TFSI for about 6 weeks when my S3 was getting it's engine transplant.
To be fair, it wasn't a bad ride. But not great. The gearbox was ok, but not great. The interior was not bad, but not great. Better than the A1 interior though.
I think the Q2 is a car for people who generally just want to get from A-B relatively comfortable, and still able to tell fellow mums at the school gates that they've just bought a new Audi.
The exterior of the car however, looks awful. And I really don't see the point in an SQ2. Dropping an S3 engine in it might have seamed a good idea at the time, but most mums don't want or need 300bhp, and it's not exactly aimed at the boy racer or anyone after a fast hatch / saloon.
They'll sell some in small numbers. I would assume most SQ2's up for sale on Audi forecourts are the cars they got in a demo's
