Just about everything in that size category.
Audi Q5 too small, Audi Q7 doesn't really compare price wise.
Cadillac SRX too small and has a horrible blind spot. I really liked the dash layout though.
Infinity-Not enough cargo room on all but the QX56, with the QX being too large
Lexus RX350- Nice ride but a bit on the small side. Third row and larger size on MDX a plus
Lexus GS460- Bigger size a plus but to much like a truck
Lincoln MKX not bad but they are totally redoing it for next year. MKT cool car but just too ugly
Porsche Chayenne Best driver of the bunch (no shit) but you don't really get much else. Wife actually really liked it and said we could get the Turbo S if I drive her old Subaru. One of the most tempting deals she has ever made. But I hate the Subaru.
Volvo XC90 The car we were originally going to get. Pretty much the same car for the last 8 years. All around not bad but again they have not kept up with the times
Didn't really consider the Merc or BMW.
We loved everything about the MDX except the looks. It's growing on us but I still think there is better looking vehicles out there. We also came to the conclusion there is no perfect vehicle (almost like buying a house). As nice and loaded as the MDX is it still isn't perfect. Three big things missing for me is no rain sensing wipers, still uses a key to start, and no On-Star. Not deal breakers but I think the first two should definitely be included.
