In the movie, as Steve pulls into the steeply banked driveway to park, there is a great sound effect of the tailpipe of the car scraping on the sidewalk.
Also, in Poltergeist 2, the producers got confused and demoted the Freeling family to owning a 77-79 custom cruiser, instead of this 80's bodystyle (which got a facelift for 1980).
