I'm wondering if anybody's ever tried this website....

I emailed them about doing multiple VINs, since it gets cheaper per VIN with multiple lookups. But I never got a response. Just asked how the VINs should be separated... space, comma, etc... but nothing.
Honestly, it's not worth a $3 gamble when I can see the paint looks good, the lines are straight, there's no obvious rust, etc. Heck, I went with a friend to buy a $7,000 Ford Mustang (2006, the new body style, with 82k miles)... that had over $7,000 worth of body work done at Advanced Collision. Was it worth doing a carfax on this car when the thing looks flawless besides 1 or 2 burn holes from the previous owners smoking cigarettes inside?? Not IMHO. The fluids checked out, and it could handle driving on the Interstate, plus it even had good tires. Why waste $30 on a Carfax when the car, itself, looks flawless??
There was another cheap VIN check site, but I can't remember what it was. Less than $10 a pop, tho. Just not really worth it to me if the body & mechanical stuff checks out.
CarFax also has a free "Flood Title Scan" for cars with flooded titles. Doesn't assure you that the vehicle HASN'T been in light flooding, but a flooded title is potentially worse because your insurance company will only pay you close to 60% of book value if you end up getting in an accident.
