Vauto's market data is superior to Dealerslink's. Dealerslink lacks data; for instance, when you input 300 miles, not enough cars are displayed. However, when we cross-check sources like Cargurus, Cars.com, and some dealer websites, we find the same cars with the make, model, trim, and year. The pricing tool also has some glitches - upon reloading, the radius is displayed. Sometimes, we have to re-enter the vehicle mileage in the competition tab, even if we've already entered it in the fastbook x tab. I am not sure if anyone having the same.
