I drive approx 2200 miles per month. I needed better mileage than the SUV I owned and compared this with the MB E350, Acura RL, Infiniti M35 and through in the E320 CDI. Having experience with Toyota products in the past gave me some heads up on this vehicle but I kept an open mind. You will not go wrong with the GS 350. My first trip was 225 miles at 26.5 MPG.
Fun to drive, fit and finish are excellent, features abound, nav system beautiful, almost any Blue Tooth phone will work (mine is an early Sony and still works), 300 horse V6 that jumps to 100 and is still averaging 27.3 MPG is just what the doctor ordered.
18" summer tires are a little rough for cruising but if you drive more aggressively they work exactly as advertised. This car hauls and turns on a dime!!
