( www.TFLcar.com ) What's the best new all-wheel-drive luxury Crossover that you can buy for $53000.00? That's the question we wanted to answer in this TFLcar Mashup review. Is it the new and refreshed 2013 Lexus RX 350 or is it the new and refreshed 2013 Mercedes-Benz GLK350 4MATIC or is it the new and refreshed 2013 Infiniti FX37 AWD? The Lexus represents the most popular vehicle in the segment, while Mercedes-Benz is packed full of new safety technology and of course the Infiniti is the most sporty of the three. In this fun TFLcar Mashup review we not only rate all three Crossovers but we also see which one is fastest from 0-60 MPH.
