What is the best way to get a Carfax Report for a used car being sold by a private seller?

I know that some Carfax reports are posted on websites for used cars, like AutoTrader.com and Cars.com, but the reports are not posted for all cars advertised on websites like those. I also know that Carfax charges a fee ($20 or $25 I think) for the reports they offer. Do you have to pay for each report individually? That could get expensive if you request reports for multiple used cars. The Carfax report I want to get first is for a 2000 Saab 9-3, 4cylinder automatic, with 72K miles. It has already passed state inspection, seller is original owner, has all service records, the car is in excellent condition and is loaded with options. Asking price is $7,400, which is above the KBB value for a private party/seller. (It's advertised on AutoTrader.com.)|||Go to carfax.com and get one.|||http://www.carfax.com/car_buying/used_ca鈥?/a>|||car fax 29.00 dollars one month fee, unlimited searches
