don't know what year mdx you are looking at but my friend's 2009 is great in snow. i doubt 8 adults in that car though. my friend takes his mdx for weekend trips with us. his family of 4 with 2 kids and 2 adults needed a thule rack for his equipments. much smaller than my 2005 pilot. my pilot does great in snow. i drove through 6-12 inches of snow couple years ago going up to stowe no problem. i did have new michelin tires, though.
