Some of those cars looked really out of place. The classics were awesome, and the exotics were cool... but why so many C5 Vettes? Why two (at least) late 90's / early 2000's Trans Ams? Quite a few later generation Mustangs too, and at least one classic coupe (a dime a dozen unless there are hidden details) parked in the corner near the beginning. They're all cars I would personally love to own, but they seem to pale in comparison to half the other stuff in there.
Maybe each of them has a story behind them, or something unique that make them collectible. If it was my personal collection, though, I'd aim to have at least one car of each generation / major style change (for example, for Mustangs: 64-66, 67-68, 69, 70-72, Mustang II, Fox Body, SN95, New Edge, S197, and throw in some Shelbys, Saleens, Cobras, etc.), and as many low production / rare cars as possible. Line them all up against a wall and you have your own story line or evolution chain.
All those cars and only one AC Cobra? For shame.
