I have plan on buying either the Acura TL or the RDX. I know that the RDX has SH-AWD, but the TL has a better technological equipment

id go with the tl
im more of a car guy

Well here's the deal. The TL is faster, and quieter. The RDX is brand new, meaning it could still have some bugs.

I think you are wrong about the equipment, if you get the tech package, the RDX has just about everything the TL has except no memory seats and no vent in the back. But with the tech package you get a better stereo in the RDX (slightly more power), not that the one in the TL is a disappointment by any means.

They are both great cars. I've driven them both and own a TL. But for me the kicker is this: Within the next 12 months the TL will be replaced with a new model. This means that if you buy one now it is going to look dated very soon. This would be the deal breaker for me right now. Dated looking cars, depreciate faster. Of course on the flip side as the time approaches for the new body shape their could be some deals around on the old shape.

The RDX is more expensive to buy and service, but it does have a more advanced navigation system that the TL.

What do you need, a car or an SUV?

Both are great cars, I think you should see if you need a SUV or a car. RDX is very nice but this is the first year it is out, and TL been around for a while, meaning most of the bugs have already been worked out.
Good Luck

unless you are going off road, get the tl, it is better on gas mileage by far. i don't know about you, but looks like gas prices aren't coming back down any time soon, if ever.
