eBay Motors

eBay allows shoppers to either bid on or buy (without bidding) vehicles from both dealers and individuals. (An initial payment may be required when using the Buy it Now function.) Buyers enter the make, model, zip code and whether they’re looking for a new or used model. They can then filter by numerous options including Vehicle Mileage, Body Type, For Sale By, Exterior Color.


On CarGurus, shoppers can search for new, used and certified pre-owned vehicles from top-rated dealers.  For used vehicles, they use their CarGurus Instant Market Value (IMV) to determine a fair retail price. They then compare the fair retail price to the asking price, factor in dealer reputation and determine a Deal Rating. Each deal is assigned a Deal Rating of Great, Good, Fair, High or Overpriced.

Tips to remember

Always do your homework and look into a vehicle’s history. The most important thing to check is the title. Titles are either “clean” or “salvage“. Clean titles indicate that the vehicle has never been declared a “total loss” while “salvaged” cars have had damages exceeding more than they are worth. Salvaged cars may be a good investment for some people, so do your homework to ensure that this type of purchase is right for you. You can use the Vehicle Identification Number (VIN) and a service such as Carfax or AutoCheck to  review a vehicle’s entire history. Additionally, these services track the location of the car over its lifespan, giving the buyer extra transparency.
When you finally select the vehicle that meets your needs and budget, you can use Openbay for service when the time comes for routine maintenance, brakes, tires, oil changes or if your check engine light comes on.
