Might be an obvious thing to many but in case it's not, thought I'd mention that you can use an extending Selfie stick with your phone attached to it and put it on Video with the camera recording facing you and easily record the undercarriage of your car this way. No lifts or jacks needed. Sort of like the car inspection mirror but better! And a great use for that selfie stick you never use and wondered why you bought in the first place LOL.
