2016 Acura RDX Best Used Luxury Suv Under 40000. From a -liter V6, the RDX gets its energy in the centre of its second-generation. Although it may possibly not be just as much enjoyment whilst the -generation turbo would be to push, RDX may be packed up having a lot of technology – among Acura’s talents. All-wheel drive is just a discount at $1,500 over standard -wheel drive. RDX has massive freight capability at feet, which makes it among the many able small luxury crossovers. Polarizing outside style, including Acura’s trademark “cheese slicer” grille, may possibly not be for everyone.
