I have a 1998 Chrysler town and country. When I tried attaching it to the vents it cracked. Tried multiple times. Should be a warning not to use on older vehicles as vents may be brittle. Also utilizing Samsung s8 plus with magnetic strip, s8 plus and set on top charger causes my phone to get hot to the touch. If this warning was in place I would have got the CD holder. Now I charge with cord.
Older vehicles get CD mount
