I used to be an Octavia fan, but after being in other cars I realised how bad the seats actually are. Haven't sat in the newest models, though. I think Volvo Estates are perennially underrated. Same kind of mileage and reliability as any other large-ish car, but way, way more useable boot space - probably the best of any non-4x4. And really comfy, and fairly affordable servicing, and not too many electrical gremlins or overcomplications (NB: I've only had experience of older ones circa 2000s). As a nice little bonus, James May actually appears at midnight in your room the first night after you buy one, pats you softly on the shoulder, and then flies away very slowly. Perks.
