It is a nice vehicle, very roomy but would most certainly not recommend CarMax as the vehicle has had a ton of issues and was in the shop for nearly the entire 1st month!
Honda/Acura produces some of the most reliable vehicles you can buy. Like our 2004 Acura RSX Type-S, the 2009 MDX is low maintenance and extremely reliable. The MDX AWD handles all types of weather (rain, snow, etc.) with comfort and style. On a recent road trip from Virginia to Florida, the MDX was great! It was like floating down the highway in a plush, comfy chair. Smooth and quiet with all the creature comforts and an excellent sound system too.
I purchased my 2010 MDX base model in July 2010. I had previously an 03 TL and really loved the quality of an Acura. I love all of the standard equipment that are actually options on higher priced vehicles. Everything like HID headlights, sunroof, leather, memory seats/steering wheel, power steering column, heated front seats, 3 row seven passenger seating, 3 zone climate control system, back up camera integrated in rearview mirror, power tailgate, heated turn signal side mirrors. Some people get on Acura for the designs of the front end of the vehicles (mostly the grills). It doesn�t bother me, its unique, who wants a vehicle that looks like everyone else�s. My only issue with the MDX is the ride quality. I find the ride to be very bumpy, does not handle any bump/pot hole in the road well at all. The steering becomes very jerky and the car will jolt heavily when going over a bump. For being a midsize crossover, it definitely drives more like a large SUV. I have read articles online where others have complained about this issue as well. They describe the vehicle like they were driving a tank, or they felt like there was no suspension. If the road is smooth, the ride is perfect. Any imperfections in the road though will clearly be felt. Living in the Midwest, we deal with snowy winters. The SH-AWD system handled well. Being that power is sent to all 4 wheels always, I did not experience any of the delay in reaction timing I have with other AWD vehicles where those vehicles had to sense tire spin before it would engage the other tires. I would not describe the MDX like driving a sports car as some have. Just because it has SH-AWD does not make it handle like a sports car. All in all, it�s a good vehicle. If you live in an area that has quality roads, definitely consider this. If you are from an area that deals with the changing of seasons resulting in pot holes, take it for an extensive test drive before making your final decision.
