In my country there are few who can have an Audi, in fact I have not seen any, the Nissan brand is not a commercial brand at all in my country either, therefore their spare parts are very expensive and hard to find, it is a matter of perspective. It depends on where you look at it, I look at it in terms of economy and if the car is commercial that does not complicate my life. In itself Toyota has always been a very sought after brand and very commercial for offering vehicles of excellent quality and durability, it seems to me that the Audi swallows a lot of gasoline, of course in terms of aesthetics and beauty the Audi would win, but it would ruin my pocket.
I love the convertible design of the Nisan, but I think when it snows and rains it will not be very comfortable, it depends on how you feel and your needs, I would love to know which one you chose in the end, in my case I would prefer Toyota a thousand times.
I imagine many importer vehicles are a rare sight in some countries.
I like how you made your decision based on what you know of the brands already. Toyota worked with BMW a lot on this new Supra.
I believe the one one of the cars that would do very well in the snow is the Audi, thanks to its Quattro AWD system.
For me, I made my choice based on looks, power, fun factor, price, and i suppose a few others reasons. Main point it, we all select our vehicles differently and I think that's why so many cars exist, to satisfy everyone.
