Nice work but got any close up shots of LOD0 and LOD1 comparisons, ie, large pictures taken from the same angles of both to easily compare. Also LOD3 needs to be optimised more, only 6042tris less than LOD2 isn't enough and you can remove some of the bigger details around then like the front rail etc, by this point the biggest thing to keep is the silhouette shape and the colour, and your final LOD (ie, LOD4) should be around 100 tris with it only being the most basic shape of the vehicle possible which is then seen at extreme range, just before the object gets totally culled from drawing at an even bigger range (although that is normally beyond most maps VDs for vehicles of this size, but final lods generally start rendering at around 500m) and the final lod should have only one material and no sub (moving) parts (i, wheels become part of the main mesh and don't rotate, and some things can even be integrated, or removed onto the main mesh before the final lod too that won't be missed or seen moving) to minimise draw calls.
Your wreck model could also do with some more messing up from the looks of it, can have things like the radio disruptor box things blown off and can twist the thing much more. Also remove and/or break the glass

One tip to speed things up is to make the wreck after you've finalized the LODs, with then having all the LODs on top of each other, applying an editable poly to all of them (and any other modifiers you want to do to all of them like FFD, noise etc) and then make the changes to all of them and it will save you a lot of work, but will need to check all of them to make sure the changes were properly applied to all of them and you didn't mess anything up but generally if your careful, its much quicker. You can also use the Multi-Rez optimizer modifier for the LODs for further optimisation a lot more on wreck LODs since any errors made by this tool are much harder to spot since the errors are normally a messed up mesh, and since the wreck is already messed up, generally other than huge UV errors, they are fine

EDIT: might make a small video on this since I'm due to make a new wreck model soon
Keep up the good work!
