The only thing I don't like about the STi hatchback hot wheels car is the scale. Since when is that car smaller than a Datsun 510?
As for the collection, I was slightly obsessed with the 04-05 body style when I had one. The silver one had a tall spoiler and matched my old car exactly. I bought that from eBay japan.
Currently I've been trying to resist the urge to buy a small scale likeness of my turbo legacy. Its like $30 or something.
