*False alarm: the listing was apparently an error.
There is a Tomica Limited Vintage Mitsubishi Galant Sigma listing currently on eBay for $1 (plus $3 shipping). The Galant may not be the most interesting car around, but still, a Tomica Limited Vintage for $4 all in.
I just bought one, but I know there is one left at the time of this post (possibly two).
