New Acura MDX’s were being sold at firesale prices. a 2007-08 was selling well below 2004/05 prices.
Personally, not a big fan of the RX. Not that great driving dynamics for me, and Toyota likes to nickel and dime on every single option.
I think the Mdx is a great deal for what it’s worth, and if you want to go cheaper, the Honda Pilot (though not a fan of the current generation styling). There’s also the X5 which I dig, though reliability is always an issue. And Mazda CX7/CX9 is pretty good…
