Seen throughout the series as MacGyver's main form of transport,
the Jeep has undergone some transformations over the 7 seasons.
First seen as an open top in season 2 with some
continuity problems seeing the Jeep flip-flop between doored and
undoored versions as well as with and without a front winch.
From Season 3 onwards the jeep becomes a hardtop model
presumably because of the change in filming location from sunny
California to colder wetter Vancouver.
In season 3 we see
MacGyver has a mobile "car phone" fitted between the front
seats as well as a fire extinguisher within easy reach of
the drivers seat.
We know from this behind the scenes
that there were at least 2 jeeps used for filming. One
has the dented front fender from a season 2 episode which
indicates that they used the same jeeps throughout the show,
moving them from California up to Vancouver with the change
of filming locations.
