Typical CQ problem areas

Now, this list does not indicate that a car will have all of these problems. 

It's actually a list of the faults that I have seen on mine or other peoples cars. 

But any car that you look at with a view to buying is likely to have at least a few of these faults.

You'll also find that this list is fairly accurate for the Coupe GT too...
