I know your pain. I have a beautiful 1:18 scale Kyosho model of my Raven black V sedan (doors, hood, and trunk open, and wheels turn) and the best V coupe scale model I could find was a 1:43 scale model in black. Still haven't decided if I want to risk trying to repaint it something close to TG. Oh well, it's all part of owning a semi-rare car.
I have the 1:43 Luxury collectibles wagon. You could fine them cheaper than that on ebay before. I ended up getting the wagon and coupe together for like half that. I don't see any deals like that now though
I considered hacking the front off a V sedan Hot Wheel to make the Matchbox wagon a V. I haven't gotten any farther than drilling out the rivets on both though. Then I ended up weighting up the Matchbox car for a Hot Wheels race at the local SCCA banquet, LOL.
Edit: Looked in my ebay history. Paid $31.03 + $5.74 shipping for the wagon and coupe together. Based on current listings I should stick the coupe back on ebay and make my money back (and then some)
