We've got a similar dilemma. My daily commute is ~30 miles round trip and the T5 drinks fuel at a quite brutal rate. I use about a tank per week at £60ish. If I use my wife's A2 I can go 3 weeks without a fillup and it costs about £40 to fill.

We really need a bigger main family car as the S40's rear seats aren't really wide enough to take the belt-in child seats, plus it's too thirsty and the A2's a bit too wee for 2 kids plus going on holiday kit. I've decided that next year we're buying a larger but cheap-ish to run car as the main family car (second hand X3 2.0d springs to mind) and I'm keeping both our existing ones. The A2 will become my commuting car and the T5 becomes a weekend car for me thus reducing its running costs significantly.

The big win here is having a spare in case of emergency. The A2 finally broke down after 130,000 miles on Monday and while it's been in the garage getting fixed it's been a nightmare getting around with one car between us.

Decisions, decisions!
