I guess in this case, both the warring parties, i.e., Tata and PMT are right in their own respect. Basically, from what I can see from the report, PMT is against this Tata bus shown below
This bus looks similar to the Starbus but it is NOT the Starbus. It was a precursor to the Starbus (tentatively called the Tata Easyride then in 2004). I would say it was more of a test mule rather than a full-fledged production vehicle thus it might be plagued with some inherent problems. It is currently a part of Pune's BRTS project.
About the maintenance of PMT buses, the less said about it, the better

Here is another PMT Ashok Leyland(?) bus, pic is mirrored that's why the doors are on the right. I guess this is a part of BRTS too.

This is the latest addition to its fleet. The front end is similar to the new BEST buses (Ashok Leyland Viking) in Mumbai
