If you own a luxury car, chances are you put a lot of thought and care into your purchase. Your car is a vital investment, even if you primarily use it for special occasions and not for everyday commutes. However, your investment doesn’t end the day you drive it home from the dealership. Keeping your car in top condition helps maintain its value in case you ever decide to sell it. If it stays in pristine condition, you might even use it for 20 years or more.
