It only works if the DMVand carfax gets things straight. I traded in my wife's car earlier this year. I decided to run a carfax report on it just because I paid for a month's service while shopping for the new car. The report showed at the time we bought the old vehicle, four years earlier, it had roughly 73,000 miles. The odo disclosure I had showed roughly 37,000 back then. I figured it was a number swap but the last three digits were different. At the time we traded that car in we had 101,000. I emailed carfax about the discrepancy, they wanted several notarized pieces of paper to correct the problem. I only had the one, where was I going to come up with two or three more to back my claim? I figured since 101K was still larger than 73K they could figure it out themselves.

All you have to do is get a programmer and reset your differiental gears as almost double what they really are. You could change your tire size as small as they go also and it would do wonders. Then, when you drive 20 MPH you are really doing about 60 MPH. At 100,000 miles all you will register is 33,000. I haven't done it but I can't say the thought hasn't crossed my mind.

 

I used CarFax before I bought my truck....

CARFAX KNOWS EVERYTHING - TRUST ME!

I stand by my story that CarFax doesn't know everything. If a DMV screws things up the owner is stuck with the choice to prove CarFax wrong (which may take expensive legal action) or eat the reduction in trade value/ fact that the government may be contacting you about odo tampering.

However, I appreciate the service CarFax provides and would still use them if I buy a used vehicle.
