I think the BMW 3 Series is about as nice and as fun of a car you can get aside from a Mustang if that's what you are looking for. I think Mercedes GLCs are often found in PS at National so they can likely give you that if you are looking for something better/fun (me personally, I rather take the 330i than the GLC). There's also the Polestar, X1 and X3.
They have lots of BMW 3 Series in the fleet the last time I was there. I think EHI in Canada are getting more Audis this year as I have seen the A3 pop up more often now.
I may be biased, but I rather take the BMW 3 Series over just about any cars in the EHI fleet.
