The iGuida Best Cars of 2011 singles out the forward-thinking Audi A4 as the Best overall car of 2011. Standouts in the traditional market classes include the Mazda 3 as the Best Compact Car, the Honda Accord as the best midsize car and the Dodge Charger as the Best Full-Size Car. Among specialty categories, the Best Reliable Car of 2011 is the Buick LaCrosse, the Best City Car is the Scion xB, and the Best Fast Car is the BMW M3.

iGuida voted the Mercedes-Benz S-Class the Best Car of 2011 for Plus-Sized. With 125 cubic feet of interior space, it takes a hefty burgher to fill it and a fat wallet to buy it. But if you appreciate huge doorways, broad seats, and homburg-clearing head room, the S-Class is without peer. Rear- or all-wheel drive and a bewildering array of diesel, gas, turbos, even a hybrid, are on tap. Base price range: $91,875-$209,875.
