I had one for a rental for a few days. I generally liked it, lots of low end juice, but I think the mid and high end were lacking. The ride seems pretty tight, but I'm not used to driving SUVs, small or otherwise.
I'm pretty sure hondata has something for the RDX,
Reflash - Acura RDX. It seems like similar numbers for the TSX reflash.
I've seen the rogue around. It seems like a nice ride. I would recommend a test drive, of course, because brand adherence doesn't always get you the best ride.
And of course, it's for her, so her opinion matters the most.
Good luck, though. I hope you get a good deal on whatever you get.
