Providing shelter for your vehicle during those cold winter months and not having to scrape your windshield every morning is admittedly one good reason to build that garage. However, another important reason that some people may overlook is protection for the other months. Harmful sun rays cause severe damage to a vehicle, not just fading your paint but also deteriorating rubber, fabric, and vinyl products such as your dash, seats and even your tires. You can increase the cosmetic longevity of your vehicle by keeping it sheltered.
