I currently enjoy an Aston Martin V8 Vantage and have had a great experience with reliability and service, so that's where I am coming from with this question. My wife is interested in picking up a depreciated Quatroporto or Ghibli S4, or an Alfa Romeo Giulia -- I know, a little bit of a difference there. She is concerned primarily with service costs and reliability and I figured going straight to the source would be the best bet on a real answer. So, what are your ownership experiences with these cars as far as those aspects? My Aston is about $1500 a year on maintenance for basic, and about $2500 for the larger every other year service. I've done tires, and mostly DIY fixes for relatively minimal expense, and I do understand that dealer service is pricier than almost any indy shop.

Thanks for any input you have on this! (personally I favor the S4)!
