If they do choose to retire other cars early, I think that the oldest Breda rehabs ought to go first. The mdbf on those cars is lower than it is on the 6ks (despite their mechanical similarities), and the body shells are older anyway.

I thought WMATA planned to eventually overhaul the 6k cars at mid-life.I could definitely see them using the 8k order to replace the 6ks as well (it might make more sense to have 2 types of cars). The Breda rehabs (2k and 3k) have the same structural issue as the 1ks (the 5ks, 6ks, and 7ks are better according to the NTSB). I doubt this the reason for for dumping cars early though.
Do you think they will use the 8k order to replace everything left and send the 6k's into early retirement? Makes me wonder if all of the fleet (except for the 7k's) have similar safety issues that were found with the 1k's and WMATA wants to get rid of them all before another crash happens.....
