I've just sold my 2006 A3 2.0TDi DSG to contrubute towards a house deposit. Gutted to see it go but need a replacement. I've been searching for a while on a tight budget and have narrowed my selction to these two possibilities. 2002 A4 1.8t with 125k miles full service history including recent service, cam belt, new disk and pads all round, 4 new tyres and new mot but just 3months tax left. or 2001 BMW 320i SE Auto with 101k miles full service history including new disks, pads all round, 4 good tyres but needs taxing. I negotiated the Audi down to £2,500, the BMW down to £1,950. Both cars are in excellent condition for the years and mileage and really do drive like they are new. I only do about 150 miles per week but dont want to get totally hammered by ridiculously low fuel economy. Which do i buy? Audi is familiar but more expensive but has full leather and shold be a little more economical, BMW is cheap, something different, very smooth six cylinder engine and looks great but im worried about how thirsty it is. (its also slower than the audi) Cant decide and the other half has told me to buy one by tomorrow or she will hit the roof. We are currently without a car. Any constructive help or experience with either model will help towards my decision.
