I contacted DNA speedometer to fix a speedometer for a Ferrari. They claimed they did several Ferrari's before and could fix it without a doubt. I told them the car is not driveable and they said as long as I bring them the speedo, they can fix it. They quoted me a very steep 350$, probably because its a Ferrari, none the less I agreed. After the fix I took the speedo home and it didnt work. They said bring it back in and they will fix it, I did just that. After dropping it off they called me about 1 hour later said they wanted me to pull out my speedo sending unit located in the transmission. I did so, they tested it and said it was bad. I then ordered a new sending unit at 150$, and wow agian the speedo wont work. After research I found out from the Ferrari dealership that the electronic part they made to fix my speedo was shorting the entire system in my car. So I had my speedo fixed from a certified Ferrari dealer. Now I had to buy another sending unit, now I spent a total of 300$ plus having the speedo fixed by another company. So I stopped payment on the check to DNA. They then called me about it, I told them not only that I wouldnt pay them but I found out that it was made with used electronic components. They then claimed I should pay them since they at least fixed the odometer, I told them interesting enough there was nothing wrong with the odometer, only the speed part wasnt working properly. Then several weeks later I got a call from the sherrifs office, they filed complaints for odometer fraud, as revenge for the stop payment. Luckily I had all the cars service records which prove the cars current mileage. If you see this company I suggest STAY AWAY, GO SOMEWHERE ELSE!!!!!!!!! The strong arm tactics and lies they use are not worth it!
