Pete, not sure the 6.5 would be quick enough.
(
There is an evil side to me that would love to buy a brand new in box Avante and then strap a 4.5 in it for a laugh. I would then put a video on that Tamiya club site. It would start with me ripping into the pristine packaging and then cut to the run up of an attempt to jump a house with it, or long jump off Weston pier. 
Quite a bit of $$$ for a quick laugh though...)
As for the Traxxas I have all the bits (although proper white front wishbones and bumper would finish it off nicely.) I did a full rebuild about a year ago but just need to get electrics in etc. Also got a new shell that needs spraying. Hopefully get it done soon if find some time.
