I do not know which one to get! I know the acura is cheaper, but I found a bmw that is the same price. So what do you think?
I've looked at the audi, but its a little too much because it just came out

I would go with the BMW but I am partial to German cars.

I'd get the RDX out of those two. You should look at the Audi Q5 and if you're not pressed for time you could wait to see how the Cadillac SRX is when it drops later this year.
