I purchased a Focus C-Max (2.0 Ghia petrol auto) from CarGiant a couple of days ago. I actually went there looking for a focus but spotted the C-Max and was stunned by it's superb condition. It is absolutely immaculate, 11,300 on the clock, 56 plateand an ex-motorbility car. I paid 7,499. It is as though it has never been used.

The test drive at CarGiant was extremely short but the car seemed fine. Having now driven it properly, I find it superb in every regard but one. There seems to be an excessive amount of noise in the cabin when the engine is revving at all. It sound like a mixture of engine noise and exhaust booming. The cabin seems to resonate this sound and it's rather disappointing. When I cruise with no throttle, the car is very quiet and glides along beautifully, but touch the accelerator and the background booming sound returns. It seems to come more from towards the rear of the vehicle.

Don't get me wrong, it's not deafening, but it sounds louder than it should be.

I took it to KwikFit and they put it on the ramp, but it was apparent that the exhaust is brand new, nothing wrong with itand I could see that everything under the car was in mint condition. So there was nothing they could do.

Is this just a known problem or do I need to dig deeper. What could possibly have gone wrong in 11,000 miles?

Any thoughts or simliar experiences much appreciated.

If the exhaust is new, could it's routing be slightly wrong and just a little close to something
