Anybody here a Licensed Texas motor vehicle dealer? I purchased a challenge car, a Mazda 3 for $400 and to transfer the title Texas has something called "Standard Presumptive Value" and for this car its $2500! so they are taxing me at $2500 even though I have a bill of sale at $400. I need a dealer to sign a form saying the value of the car is actually $400. Any help would be great thanks
