I am overall pretty happy with this model. I like how it turned out, the detailing is great and the model fit together well with minimal gaps. I like that the driver is roughly the same size as the American GI figures and I was able to do a head swap with them easily. There are enough options to make a couple of different variants. There was some flash on a couple of parts and the wheels and tracks had some hefty mould lines but that wasn't a big issue. The 50 cal. barrel broke when I removed it from the sprue (seems to be a common issue) but I was able to fix it.
The instructions are not great. The driver is added in the first step. I left him out to paint him instead and I'm glad I did because he fits in VERY precisely. I imagine if you put him in right away you may have issues adding the side panels without trimming his arm a bit. The armoured cover for the windscreen has tabs along the top for when you model it open. They should be removed when modeled closed but there's no indication of that on the instructions that I could see and I only figured it out when the gun ring didn't fit. I also felt the way the instructions have you assemble the rear wall panels is a bit odd and it was easier to line them up and get them to fit well assembling the walls first THEN the seats.
It's a nice model overall, I had fun building and painting it. It could really benefit from an updated instruction sheet is all.
