I think the price is too high as the second hand Volvo price is very low. Your friend better to go to some 2nd hand car shops to check the market price. E.g. Kowloon Bay, Old airport etc.
Volvo's quality is quite good. It is very safe and easy to handle. The only disadvantages are low resale value, relatively high gas comsumption, and the "looking" is a little bit "old style".
Moreover, I am not sure whether it is easy to find some shop for repairing Volvo as it is not a very common European car like Benz or BMW.
