I rode 6210 today, that bus is nowhere like how it was in October last year. There was a minor problem with one of the vent windows, and that was like the only improper thing I found in that bus back then. The bus did sound real awesome and the next-stop sign was working, and it was also pretty quick! Now to today, the next-stop sign still does work, but the bus is slow, it does not sound that awesome anymore (with the loud heating on, it may sound different if it is off), and I found something that is really dangerous that could break any second. This bus is also really bouncy, and kind of reminds of my 6651 ride in December. I was expecting it to be like 6237 (my fav, it sounds brand new), but turns out it is going to be gone pretty soon like all the others.
