LOL .. I have an old school flip phone.

BUT, I have a nice digital camera now and I can operate that. I have a video camera which I am working on. Started videotaping my injector rebuilds (son is filming of course). I would suggest both photos and video. I would video tape the drive so you can "feel" the car and hear it too. Photos work for certain things too. I suggest at least 15-30 minutes once over the car. Also, folks seem to gravitate to a certain model. Having folks which "know" about their car and broken down by models may be helpful. Just my .02 cents.
