I bought this for MPG but got so much more. Great stereo also plays MP3. I am getting 37 city & 46 highway because I drive really S L O W. If I wanted to, I could cruise at 80 miles per hour in silence & comfort & still get great MPG. Absolutely nothing to complain about after 4 months. Quality of construction is like a Rolex. I am so lucky to save so much money with the purchase & mileage. I expect for gas to hit $6 per gallon or more & I am so lucky to be ready.
Huge gas mileage on regular grade, not premium like Smart or Mini. Great stereo also plays MP3 & has connection for iPod or XM radio. Quality of construction is impeccable.
I can not think of one thing considering the extremely low price I paid.
