I bought a car from a second hand car dealer at the end of September 2012. Since then it has developed numerous faults which I have had to take to a garage to get repaired under warranty, apart from the repair of the dual mass flywheel which I had to pay £450 for.

I have hardly drove it a few days without another fault developing and is now still in a garage under repair - they have had it for 2 weeks and didn't supply me with a courtesy car for a week, so I had to rely on public transport, taxis and borrowing my parents car to get to work and back.

So far it had had a new turbo, intercooler, alternator, inlet manifold, thermostat, dual mass flywheel and a fuel filter and now they are saying the turbo is at fault again. What can I do?
