It’s always good to keep your receipts documenting your service and repairs to your vehicle. But that usually only helps when you are selling your car to another individual. When you trade in your car, the dealer is not likely to look through those receipts to evaluate your car. In addition, due to Privacy laws, many dealers will ‘trash” any personal documentation/receipts etc left in your vehicle to protect themselves from litigation. This results in no service documentation available for future buyers. But if it’s reported to Carfax or Autocheck, you have everything you need in the history report and you don’t have to share your personal information with prospective buyers or fumble with receipts when trading your vehicle.
Most reputable shops report to Carfax and/or Autocheck. Make sure yours does so you can easily prove you have taken care of your vehicle. It may very well help you get more money for your vehicle.
Additionally, make SURE the odometer reading on your repair/service bill is the actual odometer reading for your car. A typo or mistake at a repair center can show up as an “Odometer Discrepency” on your History Report. This can cause you some headaches when you trade and possible loss of value for your vehicle.
