Hello !
Yes, I have a number of SEPTA and earlier PTC trolleys -- see my FLICKR Photo Album of ALL of them shown on the streets of my Layout - LINK BELOW

Here ALSO are some photos of just a few of mine also -- and yes, MTH did do 2 SEPTA trolleys - one in the early 1970's Goldenrod scheme and one in the 1980's "GOH" All White with Red & Blue band around the body.
IHP does the Kawasaki Car as a kit but you must assemble and paint and detail the whole car. CORGI did some postwar PCC cars painted in the SEPTA and PTC schemes, but they are long ago discontinued....as are the earlier MTH "SEPTA" and "PTC" PCC cars.
Regards - Joe F
