Very good question. Fwiw the latest/last v70 iteration is very spacious. Better than the previous model up until 2007 was. But not like the 240 I don't think.
Edit: a volvo 745 can, according to a thread on a swedish forum, swallow a 200x120 cm IKEA bed (with the rear seats down obvs). An option perhaps, no idea if they're common in the UK.
Good mpg and aerodynamics are non negligible, you say? I guess you need to go semi-modern-ish in that case. I've seen a few nissan estates that look fairly huge. LMGTFY.
