"This is a very attractive set with some cool pieces and interesting ways of putting parts together. However, the first thing I noticed when building it is that it felt very narrow. The vehicle it's modeled after is a 2 seater not a single seat, and comparing the final model to the real car's photo, it's easy to see that it's way too thin for how long it is. It still looks great, but it doesn't have that same wide profile supercar feel to it.
It also has a lot of stickers, which are nice thin and clear ones, but they'd be so much nicer as a stamped graphic. I'm guessing that McLaren wanted their logos to appear in specific places a certain number of times, and stamping the parts would be too expensive. I just think that stamped parts are more attractive because I don't have to worry about parts being crooked, having fingerprints in the glue, etc.
Finally, the spoiler is attached with a really weak method (see photo). I can think of several potential ways the arms holding the spoiler could have been connected securely. The way it's attached by default makes the joint that controls the spoiler angle stronger than the base of the armatures, so just positioning the spoiler can cause the whole thing to fall off. It's just a frustratingly week attachment that isn't very easy to reattach.
It's still a great model and looks nice on my shelf until the parts are needed elsewhere."
