We have the L40 models (not L60), which as best I understand are pretty much the same, just without the emissions equipment on the L40.
So the L3540, L4240 & L5740 are Grand L's and roughly equivalent to the L3560, L4060 & L5460, compared to the L3200, L3800 and L4600 which are our standard L's, and equivalent to your L3301, L3901 and L4701 respectively.
