Our Rides

Honda Pilot

Honda Pilot 4WD SUV

Our second touring vehicle is Honda Pilot 4WD SUV.  It is equipped with leather seats, sunroof and a great sound system. The vehicle was chosen primarily for its roominess, smooth & quiet ride, comfortable seats and large windows.

This is a great choice for private tours, families and small groups.

The Honda Pilot is excellent for extended journeys and multi-day trips to surrounding states.
