I just got my first actual MicroSizer brand car (with a yellow Toyota bB open deck shell), and I have to say, the quality is very noticable on these cars. While putting it together, it was very apparent that this chasis was thoroughly inspected and even adjusted before packaging to correct the steering. I am impressed! This is my sixth car mini rc purchase, and I have to say, it's the best one yet. The ones I bought before are: Panther, Shen, Z-Car, P-Digi, and Lxx Char-G.
This one is very quick (for stock) and turns on a dime. I guess both it and my Z-car have about the same turning abilities, but this one goes perfectly straight, and the Z always curves a bit. Well, I guess I see what all the fuss is about.

I am going home now and going to slap a 3.8 motor in it. Also, this shell would be perfect for a blue headlight mod. We'll see about that, soon. Fun!
PS:: this open deck is also beggin' for a dual-cell mod.
