Saw this on ebay and thought I could cut it down to match my MTH Santa Fe coaches.  It is extruded aluminum that is thick and tough. Just getting the car apart was a job. Lot of compromises involved to get this to work out. Cut some off the bottom of the car and raised the floor. Put in seats, took out the old seats in the dome and put in some of the Great Trains seats I still had.  Gary Raymond ball bearing wheels pickups for the lights, and man does it roll nice!  I had to modify the ends also
