I wanna buy an Audi that stands out a bit, but I can't decide whether I should get the 2010 A5 or the 2008 A8. They're more or less the same price. How does the two cars compare in terms of driving experience, reliability, repair cost, comfort, resale value etc. Would be very helpful to get some feedback from someone who has experience with both cars

 

A8 is based on Bentley Flying Spur.
A5 is based on VW Passat CC.
