full-size SUV: i'd take a Patrol over anything else (including a Trooper, Pajero, Prado, and Expedition) without a doubt. then have it converted to 4x4...
mid-size sedan: Cefiro gives the Camry and Accord stiff competition
compact sedan: while i'd prefer other cars to the Sentra, the Sentra appeals to luxury types nonetheless
pickup: a Frontier is arguably better than a strada or hilux or fuego or ranger, imo
minivan: hmm, well, the Serena has its appeal too (great interior)... if only it looked better on the outside
Nissan quality, reliability, and durability are on par with Toyota and Honda... parts are cheaper and more available than Honda parts i think
