Absolutely nothing. For people who are afraid of the future; they might not like the "futuristic" look of the car.
When the oil light comes up, most likely it's because it needs a little bit of oil, or because it is time to change it.
The rear door takes two hits on the key-less remote to actually open, but I can live with that.
The reliability and security that it offers are priceless. With a wife and a new-born baby, I could not be happier knowing that they are safe in a car that can handle the road very well.
The spacious interior and the easy access to controls are a plus. This adds security and it's safer for the road, since you don't have to take your eyes off the road to change stations or change the volume.
I hope by "oil light" you are not referring to the oil pressure warning light? If so, you should not be waiting for it to come on to find out it "needs a little bit of oil"? If you do, look forward to a short, unhappy life for the engine in your Aztek.
The two clicks to open the doors is something you should be able to change (I did it on my car). Look into the remote entry instructions in your manual. I believe this was covered under "Personalization" settings.
