Recently the National Automobile Dealers Association issued a media release stating that premium luxury vehicles hold the highest annual depreciation rate among automobiles.
Not a surprise, really, considering luxury cars start with high prices, and recent consumer preference for spending less on smaller vehicles due to gas prices.
Lasting Luxury
The NADA Official Used Car Guide data shows premium luxury coupes and sedans held four of the top 10 spots for vehicle depreciation for the year, with an average replacement rate of 43%.
Keeping your car for 15 years or for 225,000 miles can save you over 30 grand. It turns out that most people trade in about every five years so these findings are based on upgrading to a new, identical model every five years.
