I've got a 2004 Audi A4 Avant 1.9 TDi with 86,000 miles. It still looks smart, I like driving it and it has generally been reliable. The car got through its last MoT fine but on its latest service the garage picked up a range of minor repairs. Plus it now needs a new cambelt kit. The cost for everything will be £900.

I don't know whether it's best to pay and keep the A4 and hope it keeps going another five years, without huge repairs, or whether it's now time to replace it. We need fairly decent space as we have two young children and regularly need to transport small/medium furniture for my wife's small-scale business.

The car is used daily for lots of short runs as well as longer ones of up to 15 miles (once/twice a week), so am concerned about DPF issues if we buy a diesel. I have been thinking about the new Mazda CX-5, should I get one of these instead?
