I prefer Nissan. Infinity to Nissan is like Lexus to Toyota or Acura to Honda. I love the early 80's designs like the 240sx 300zx & Skyline models. You still see many of these models on the road today. Alot are being shipped down to Canada from the United States.
Longterm, Nissans and Infinitis are generally problematic cars (one in the same), so in general I would never invest in one again. I had an 09 Maxima and I went through hell with the amount of electrical issues I had with it. But if I had to choose, Infiniti only because of the luxury factor.
their the same thing its just money talking only one is higher cuz of brand name and they have the same engines dependin on model
