Since its introduction, the A4 has always been one of the most popular models in the Audi line-up. One of the strongest sellers for Audi, the A4 offers brilliant handling, a great range of engines, and impressive fuel economy for a non-hybrid. The 2019 A4 was offered with either front-wheel drive or all-wheel drive, but since quattro AWD is such a hallmark for the Audi brand, finding a used example with quattro AWD is much easier than when shopping for a used version of any of the A4's competitors, which is nice. The base engine produces 188 horsepower, with optional engines offering up to 349 horsepower.

We have already mentioned what an excellent choice the A4 makes as a pre-owned vehicle. Well, the A5 is everything that you love about the A4, but with more style, more standard power, and legendary quattro all-wheel drive coming as standard equipment. The A5 was totally redesigned for 2018, making it far more attractive than its competitors, with styling cues borrowed from the bigger A7. Standard features are excellent, and even the base engine produces 252 horsepower. If you want more power, there is an available V6 with 354 horsepower.

When you need a lot of space in your Audi vehicle, including enough space to seat 7 comfortably, look no further than the Audi Q7. The Q7 was the Audi SUV flagship in 2019, with a super luxurious interior and available features like an absolutely incredible stereo. And while you would think that all of that size would come at the expense of the handling, the Q7 will probably surprise you with its athleticism. All-wheel drive is standard, and the available air suspension makes for an incredibly smooth ride. The standard engine makes 248 horsepower and the optional V6 produces 329 horsepower.

Like several other vehicles on this list, the Q3 was totally redesigned for 2019, giving it impressive tech and sophisticated styling that you won't necessarily find elsewhere when shopping for a used compact SUV. The 2019 Audi Q3 sports a soft and comfortable ride, great tech, and standard all-wheel drive. Its appealing design and excellent reliability have made it popular, and finding a used example for a good price is always easy. The Q3 comes equipped with a turbocharged four-cylinder engine that produces 228 horsepower.

Not many small sedans have been offered with all-wheel drive before, but if there was one brand that was going to do it, it was Audi. The A3 was Audi's most affordable model even when new, and it's an exceptionally good value used. In fact, in 2018 it won the Best Small Car For The Money award from U.S. News. 2018 also saw heated front seats and two USB ports added to the standard equipment list. Handling is excellent, and acceleration is a standout among subcompacts. The A3 comes in either front-wheel drive or all-wheel drive form, and with either 186 horsepower or 220 horsepower.
