I am new to Maserati and looking to acquire Maserati QP. I am wanting a low mileage (under 40k) 2007-2008 car and think that I can pick up something good for £20k-£25k budget? I am told that the ZF auto is better than DS - so this is getting my attention. However I have seen a car advertised with the 4.7 engine rather than the 4.2 which seems more common. Can anyone advise me here on the pros and cons? I know that this is a dumb question, but hopefully you will forgive me as a Newbie?
