how does Audi A5 compare againts Nissan Altima Cpe 3.5SR

Hello,

I am currently planning to buy a new car and I have shortlisted 2 cars

Audi A5 Coupe Premium plus (base price around 38K) and Nissan Altima 3.5SR (base price around 30K)

I am planning to buy an automatic transmission and the thing that holds me back from buying an Audi is that it only has a I4 (212 HP) engine whereas the Altima has a V6 (270HP) engine.

Here is a link that provides a detail comparison between the two cars

I am planning to finance this car for 5 years and would like to sell it off at the end of 5 years.

I would really appreciate any advise :2cents: on the power / torque comparisons of these 2 cars and which one would be the best to invest?

Thanks!
