A previous generation 5-door Honda Civic would be sufficiently capacious yet sufficiently dull and reliable to be a safe choice. No, not a Type-R, a boring one. Not a Type-S either if you're a new driver and want cheap insurance. Most are owned by old people so a higher mileage one may be both cheaper and in better condition due to getting enough longer runs.
An old Primera would be suitably horrible. I loved my W reg diesel at the time, as it was the first new car I'd had (company) and it had climate control and leccy (front) windows. It was pretty decent for it's era, but quickly became dated and outclassed. It was dog slow too for a turbo diesel – 90bhp iirc. and wasn't without it's problems (head gasket).
What about a Mazda 6 Estate? I had a hatch and it was a great car – 2litre td 140bhp (look out as there are some 120bhp models about) and bags of torque. I had the TS2 model which is worth looking for as it has climate control, full electrics including partial control of drivers seat, electric sunroof, cruise control, traction control, stability control, steering wheel controls, 6 disc in dash autochanger, Bose amp, sub & speakers, leather trimmed bits.
Wow, I'd forgot about an Avensis when considering horrible cars. Dull, uninspiring and absolutely horrible to drive. I've driven three fairly new ones (< 5yrs old) and they were all horrendous.
