Our RDX is as solid as can be. It has no problems handling grades. Matter of fact, it is tough to keep it from racing off. The car has plenty of power, is very comfortable and has excellent ergonomic design. It does eat up fuel, but I'll take its appetite over my old Maxima. It truly is amazing, Acura is in a whole different class.
Heated seats, turbo (a lot of fun), power, and incredible handling.
Memory seats w/auto entry/exit feature, rear air vents, not much else.
