Welcome.
The reason your wife's car is getting less MPG is that the car has to warm up to operating temperatures. In doing so the car consumes more gas. So short trips will never lead to good MPG. The colder it gets the worse the effect.
On to the radio, I have had good luck with hideaway set-up. You will pay a premium for the convenience of a unit pre-built and the sound will be fine. Can you build a better unit that sounds better for less? Yes. But time and convenience comes into play also. The Best thing I did for my set-up was to swap out the headunit. I then added a small sub/amp later.
