29. BMW 7 Series

Considered to be one of the most desired flagship series on the market when it comes to sedans, the BMW 7 Series, unfortunately, doesn’t do too well when it comes to resale value. Due to how advanced the cars are technologically and that they are quite expensive to fix, most people aren’t interested in owning an older BMW without warranty protection. Also, BMWs aren’t known for their long-term reliability; therefore, you may want to rethink purchasing one if you hope to sell it one day.
