Just looking around at a few different cars for a daily mileage eater and after a few suggestions (and links if you have them) to cars that would fit the bill.
Few things it must have.
Decent MPG but can be petrol or diesel
Fit adults in the back, but doesn't have to have 4 doors
Largeish boot, can be hatch, saloon or estate
Needs to be a larger car, not a polo etc sized car
Needs to be cheap £700 max
you can pick up a lot of mid 90s volvos for around the £500 mark with tax and MOT. MPG depends on engine, my 2.5 isn't great unless you are on a run when you get 32.
