UGH THE WORST!

ABS plastic
Minichamps is the saddest purchase in my collection (I've got 3 of them).
Having diecasts is always a great feeling if you like touching them; fondling their hinges and oogling at their insides.
I just like looking perfect detailing. Resins are perfect for this. So long as you don't pick one up nor take it apart, the resin model will feel like a million bucks. Why do I say this? I wheelswapped 2 Ignition resin models recently, and decidedly photographed the process since I was curious to know what the insides of a $300 (Canadian) model are like (so you don't have to!).
This is the recent R33 GT-R.
The seats are attached to the MDF base. How are the seats though?
Piping is part of the base's one-piece thing. The muffler is an separate piece that is glued into place. The assembly of this may differ with other IG models though.
Axle on the front, no engine (obviously). The silver piece in front is there so that you have an intercooler on the front-side. Notice that its a separate piece? This make it look much more realistic when you notice that gap between the intercooler and the mesh.
Individually mounted pieces on the back, not sure if I like that. It's good for getting negative camber, and adjusting ride height, but it's also subject to inconsistency.
I'm unsure what those silver screws are for at this time, I'd guess it's to fasten the MDF insides to the resin shell.
Front axle is installed with a dab of rubber cement. That is so the wheels don't turn. The slot the hubs fit into is already snug, so all you have to do is pull.
I thought it was a nice touch that IG uses cardstock to conceal visibility of the insides when viewing the wheels from the outside. Looks like hand-made and less like mass-produced products the more I disassemble this thing.
After swapping the wheels on the white and purple R33, this is what I have now:
