If you need the driving experience, then X3 with m-sport or the DHP adaptive drive. Nothing beats it. The Q5 would be next of choice but it can`t really rival the X3. It`s also the hardest to deal with in terms of negotation off msrp. The RDX is an excellent vehicle. Its probably much better in carrying people and their stuff in luxury (again the cabin materials aren`t excellent but the value is there that none of the other 2 can match). The RDX is directly related to the CRV platform, down to the AWD system. Maintenance costs are not even a question compared to the RDX. Finally you would be purchasing new rather than CPOed.
BTW before we all recommend this warranty and that warranty and CPO or BMW extended please read or submit the fine print here. The details are ever so important. All the fluff that MFGs put out there hides the true nature of whats covered and not, so be careful.
BMW and Mercedes Build Beta Products!
Lexus build Release Candidate Products!
Why does this matter?
CAUSE EVERY TIME someone says Lexus has better build quality, one should consider what Toyota their Lexus Engine and chassis platform comes out of and how long that part has been tested in the real world!
