Mechanic owned... Hmm Id prefer a "Technician owned" truck myself!.. Nonetheless, I don't like to egg on any diesels actually, The last vehicle that drove like an a** around me was a pimped out prius, I pulled out nice and easy because i seen him in the distance and with the 100 over injectors i didnt want to light into it and him think i was another one of the smoke blowers, well after he cut me off and almost caused an accident between the cars in front of me, i wished at that time i had let her rip!
