What I'd REALLY want is a 2nd gen Barracuda, or a 73-74 Runner. Those aren't very common, and I love those cars.
Do you mean the '70-'74 Barracudas? Matchbox has a pack of 5 muscle cars out now that has a medium blue Barrcuda in it. I think that pack also had a '69 Camaro. Once in a blue moon Hot Wheels will put out a convertible '70 'Cuda but not very often. The last time I got one of those was a couple years ago, and I think it was a Treasure Hunt car or something wierd like that.
Johnny lightning has a line of 1/24 scale muscle cars out now. Detail is nice. As far as Mopar stuff goes, they currently have a yellow Super Bird, opening hood and doors, steerable front wheels. A few month's ago they had out a FM3 Panther Pink Cuda with shaker hoos scoop, louvers, and Go Wing. Unfortunately the door don't open. I happened to find a White Lightning version that has a white interior and white Crager rims. It doesn't look as nice but I got it because of its rarity, 1-7% of these cars are White lightning, according to JL.
I don't go out looking for White Lightnings or Treasure Hunt cars on purpose to collect. It consumes a lot of time and $$$. I just bump into things once in a while that I like when I'm already out shopping. I met one guy that has literally a whole garage full. Now he doesn't want them and can't get rid of them.
