I have noticed these redone amfleet I cars that have grey walls, blue seats, and blue carpeting. If these are concept 2000 cars, it is a grave mistake to continue rebuilding cars to this design. I have had several bad rides on these cars. Most recently, the restrooms were not functioning on 391 out of Chicago. The smell reminded me of the Bear's offensive game plan, and of the workmanship in these cars. I noticed a loose piece of wall paneling that vibrated noisiliy as the train went down the track. Also, the seats are uncomfortable because the armrests are too short. This sounds weird, but with short armrests, it is hard to find a comfortable sitting position. In general, these cars are not impressive.
