I'd definitely want to see the doll before I consider buying the car.
Really, I'd prefer not to have more than 4 of any character, because buying variants is money that can't buy unique characters, and those 4 would have to be quite good. I mean, I already own 3 Ghoulias and 2 Draculauras, and will no doubt have a 3rd if I keep the 2-pack one, and a 4th when the Halloween doll comes out. It would have to be good for me to have a 5th version, or worthy enough to maybe sell the 2-pack doll. That's if I consider it decent enough to actually want to buy it, all we've seen is the head.
