5. 2014 BMW 3 Series 328d
Selling price: $35,508
We featured this as one of our best luxury cars under $40,000 last month, and now it's dipping even further below that mark.
The BMW 3 Series isn't so much the "cheap BMW" as it is the sought-after Beemer that just happens to come in at that price.
Packed with great features including a heads-up display projected onto the windshield, blind-spot detectors in the rearview mirrors and a freestanding iDrive screen for communication, navigation, entertainment and apps, the 3 series doesn't exactly come up short on perks. In fact, it piles them on with features including a pushbutton starter that shuts the engine off when idling, a 240-horsepower engine that gets 34 miles per gallon on the highway, adaptive all-wheel drive and hands-free trunk access.
Know what else squeaks into the 328 series? A turbodiesel model that gets a mild-mannered 180 horsepower, but boosts fuel efficiency to 45 miles per gallon on the highway. Those are a lot of options at a price that's supposed to offer luxury car buyers very little.
