Nissan

Does anyone thing that the nissan armada and the infiniti q56 look exactly the same, except the front grill and maybe minor differnces.

Yes, infiniti is the luxury line of nissan, lexus is the luxury line of toyota. the q56 is the same vehicle as the armada, with larger chromed wheels, luxury package to include heated seats, navigation system, upgraded stereo, leather, standard sunroof, etc. sometimes, they offer beefed up engines in the luxury models that are not available in the standard mainstream products. jaguar is actually a gm product, jeep is a product of daimler-chrysler. sometimes domestic and foreign companies will share the same vehicle to get their name into the market, for example the mazda pickup trucks are actually ford vehicles. mitsubishi starion and the dodge conquest are the same vehicle. dodge stealth and the mitsubishi 3000gt are the same vehicle, etc. mercedes-benz is owned by daimler-chrysler.
