The Lexus RX refuses to give up its title as the Luxury Crossover of the month. With over 1,500 more units sold than last month, the RX is the crossover to beat. With the right price and quality, Lexus has always been a great choice. With a comfortable interior and stylish exterior, the RX continues to deliver. Only one other vehicle even came close to the number of units sold, which was the Buick Enclave with 5,241 units sold. With Buick sales on the rise for their Enclave, we might have a different crossover up here next month. Can the Buick make up that almost 1,700 unit difference?
