What are your favourite slot cars ?

[Coelacanth]

The auto world ones I like the best so far....

I have acquired a bunch of Auto World (modern versions of AFX Magna-Traction cars) slot cars and although the bodies are impeccable, the chassis' are significantly inferior to the originals. The wheels in particular are crap. All of them use the same wheel design from what I can tell, unlike the several designs used by the original AFX cars...and the design kind of looks like crap. They are also not easily swappable with the old axles. I also think the chassis top plate with gears is substandard, and because of the new design, you can't easily swap the top plate with older chassis' or vice versa.
