Are you thinking about buying a new car? Considering how much one will cost is only half of it. A key sticking point for a lot of buyers is how much value the vehicle will lose once it’s driven off the lot. What’s even worse, the car will continue to depreciate in value. Typically the value of a car will lose an additional 10 percent each year.

Don’t purchase a car beyond your means. Yes, a luxurious vehicle may be a fantasy for some, but owning one is risky. Luxurious cars often see the highest levels of depreciation. Some even lose as much as 50 percent of their value in the first couple of years.

Depreciation is often overlooked when people are deciding what car to buy. Even if you’re planning on buying a used car, it’s essential to understand what you are getting into before making a purchase. Here is a list of 50 cars that are rapidly losing their worth and why.

50. BMW 4 Series Convertible 420d Sport

With a price tag of £44,535, the BMW 4 Series Convertible 420d Sport had a price drop of £13,475, retaining only £31,060 of its value. An overall 30.3% plummet in value.

The BMW 4 Series is a comfortable and well-equipped convertible. You could be fooled at first glance. BMW chose to go with a metal roof over a cloth one. Great for keeping it quiet and reducing noise, bad for weight. The car has less than 3-star reviews online, and even though the car may look cool, there’s a lot more to consider.
