Both cars haven't had any problems. Just the usual, annual services, oil changes, etc. The DB9 is also a 2005 model and we've had it for about 3-4 years now and it's running stronger than ever. And the F430 hasn't had any issues that I'm aware of. Just they same annual services and oil changes... Hope this helps. My dad daily drives a Maserati Quattroporte but now looking into a 2011 Jaguar XJR L in the near future...@Blue4reF1: As your father owns both of the cars, how do they compare in reliability and running cost?
