Do you use your own proprietary system for car valuation/pricing?

This is the repair section of the site, this question should go to the home office, click on contact me at the bottom of the page and send them this question, Happy New Year !

I calculate them all by hand and go through 210 rolls of adding machine paper a day. I hate my job.

All the car valuation sites yield different prices when I check them so I would say yes, each one uses different methods or data. Poor Bob.

I used to use an abacus with one of the balls missing....

No wonder your numbers don't agree with Edmund's.

Exactly.....

Edmunds uses a random number generator. Bob is probably more reliable with his abacus.
