For the car shops that require an appraisal and I am pretty sure the OP's did not like 99.9% sure I will keep my keys walk out to my car with them unlock the car for them and if they need to drive it I will ask if they can get in the passangers seat and I will drive it with them. If they must drive it I will go with them and then immediately get my keys back. I give every impression I am in the market for the car and ready to buy within the week until after seeing the numbers. Thats when I have to look at other vehicles before making a decision and there is no number that will make me buy today. Now I have done hundred's of car shops and have honed my skills. I have done the negotiating ones where you have to negotiate down 5000 less than msrp and still not buy the car. Take my advice or leave it it's no skin off my back. Also $30 is my minimum for non video and $40 for the company OP did it for.
Side note: the MSP which OP did for starts them at $17 then goes to $19, $21 or $22, $25,$27, $30, $34, $40, $50, $60, $75, $100.
Shopping Western NY, Northeast and Central PA, and parts of Ohio and West Virginia. Have car will travel anywhere if the monies right.
