Got distracted by a little side project while working on my pub - still in LDraw unfortunately, hope to realise it as a real model some day though.
I present to you, a miniature version of the great 1996 Model Team set #5571 Black Cat!
It's in 8-wide minifig scale (actually at its widest it's 10-wide, just for the lights on the side). Seats 2 minifigs in the cab due to half-stud offset seats. Unfortunately I didn't have room to also offset the steering wheel so it looks a bit funny.
I really wish they made brick versions of those wedge plates that are just in front of the doors, the stud gaps don't look great. Also I'm slightly afraid that the exhaust pipes will fall off in a real model - they're only held on by the end of the upside down tap sticking into the stud hole of a headlight brick. Might do better using the same technique as I used for whatever those grey things are sticking out above the wheel arches.
Yes, the wing mirrors are cleavers.
