Owned 2003 MDX and was very pleased with the reliability. Did not want another MDX but ended up getting this one instead of the RX350 due to Value for the money. RX350 is actually more expensive than the MDX and does not offer 3rd row seat. Vehicle drives great so far. A couple of things. a) It required premium fuel. Wife did not know and put in plus instead. This caused the vehicle to jerk when transitioned from first to second gear. One premium fuel is used, problem went away. b) Leather seat is fairly easy to get dirty. Interior is compatible with RX350. Lexus used to has much better interior in the past but 2010 RX350 has similar leather grade as MDX 2010.
Very roomy and has good storage compare to RX350.
Improve gas mileage. Better leather qualiy which does not get dirty so easily. Offer 2 wheel drive to improve gas mileage. Allow regular fuel without causing vehicle to jerk. Allow individual option upgrade instead of bundle package.
