At present I have a 2002 Vectra SRI 130 Estate which is great for size, however it is just costing me too much to run. The only problem is I am still paying for this car (loan not finance) but I could really do to change it. I have been scouring the net looking at astra mk4/5 estates, in the hope of finding one that I can pretty much do a straight swap for.

Ok I know I may be holding my hopes to high on a straight swap but I have been looking at diesels with slightly higher mileage and older cars and there are a couple out there, but I wanted to see what you lot thought.

I'm not bothered about performance, got to think more along the lines of cost effectiveness with the baby on the way, so wanted to know what your recommendations were?
