We bought about 75-80 of the remaining 3016/3616 series last fall because we like those Mitsubishi models so well and they are Tier III. The majority of those are gone now, maybe a couple dozen remaining on our lot. I think by the end of March a customer will be hard pressed to find one. Quite a few dealers stocked up on these. The last few hundred went fast out of the distribution centers.
I will say the new 1533 looks nice, but it does come at a higher price and with a more complex engine. It is a little larger and heavier, which ought to be about perfect.
If a person wants a 3016/3616, they better get with it.
