I kind of disagree with the OP. I have taken the Metro now and then for the past 5 yrs and 5 yrs ago, the Metro definitely needed some kind of facelift or refreshment. In the past 2 yrs I definitely have seen them put in some improvement with the older cars with newer cars and there aren't as many delays on the tracks anymore. I kind of wish though, that some of the cars would go through 1 am (usually the last trains are ~11pmish), I guess that would be my only gripe.
