Without Carfax I'm not sure I could of purchased a used vehicle and felt confident that my purchase was an informed one. My time is valuable and I wanted to make sure I had good information about a vehicle before contacting the seller. Using Craigslist, I saw many vehicles that, from their pictures, looked like a contender. After generating the Carfax report, red flags that eliminated a vehicle from our search appeared. The red flags were due to odometer discrepancies, undisclosed salvaged titles, originated out of state, structural damage, and cars that still had liens against them, I generated about 35 Carfax reports before finding the right car to pursue and buy. I highly recommend everyone to use Carfax as a resource to help their vehicle search. You'll feel better making an informed purchase. I know I did.
