I have the same problem as Ms. Burress. I'm 69, and I had a hard time uploading pics of my 85 Chrysler 5TH Ave. Justin took care of it in short order, by telling me to take and send pics from my cell phone to his cell phone. My computer had the PDF which is not compatible. Excellent all around!!!
Sold my motorhome and the tow vehicle separately with 2 different ads in 30 days. I was expecting much much longer time but when you advertise nationally the number of people reached are huge. Can't get exposure like that anywhere else. Highly recommend.
