Already driving another car for work and etc so the porsche would be more of a second car... The a5 have been reliable other than the clutch failure I had earlier this year which I was lucky enough to have it covered by the warranty... Other than the a5 has been incredible, is just a 12 yo car doesn't sound appealing when is come to reliability, but how would I know since I haven't own a porsche before
I was going to suggest the 911 anyway, but now you've stated the A5 is actually a second car - what are you waiting for?? Daily drivers can be sensible, second cars/weekend cars should be a bit mad. An A5 is very nice in many ways, but as @IL put it, it's not a true sports car.
