Two big new test cars join the Consumer Reports fleet: the Chevrolet Tahoe and Suburban. We also drive the GMC Yukon Denali XL and Cadillac Escalade. First impressions are that these big SUVs might be something of a disappointment, but there's no question that they get expensive. We then tell the conflicting tales of two BMW coupes: a 435i press car and our fabulous M235i test car. Then we discuss a BMW 2-Series competitor, the Audi A3. Finally we ask our viewers to weigh in on a question: what is the worst car of all time?
