XC60 has good reputation and is reasonably priced, it has 5-year free maintenance. And it's real Volvo.
Q5 is based on Audi A4, good handling and fuel efficiency, good 4 wheel drive for city and highway driving. Good price too, and it’s real Audi.
Test drive both, you will like them.
RDX is refined Honda CRV, both are based on Civic. It might be an economy car if the price is much lower, but for $36K?
By the way, there is no such car company called Acura, it is a division of Honda company, sell re-fined or re-badged Honda cars.
