Used luxury sedans with price figures that don’t reach $40,000 provide value for money, at least if you know where to look. Don’t do your homework on the subject and you could wind up spending more than you thought on a clunker. But if you know what you’re getting yourself into, used versions of models like the 2018 Infiniti Q70, 2018 Mercedes E-Class, and 2018 Audi A7 can be yours at prices that suit your budget and financial well-being. There are nine cars on this list, each offering qualities that make them good choices. Some models have posh interiors; some have massive cargo spaces. Then there are those that have power and those that have edge-of-your-seat driving dynamics. All that matters is you know what you want, and you’re prepared to spend on it.
