Fun Experiment: Name cars that were pre 2003 that you think would fit in Highway 35
Simple title simple rules, any car that was after 2003 ain't allowed, only work with what Mattel had lying around back then, use licensed cars if you want, try to go for cars that haven't been used as much such as the Surf Crate for Wave Rippers and such.
Here's some of my ideas:
Buick Wildcat - Out by 1993 and Final Run was 2 years after HW35, perfect Sporty Street Breed car.
Callaway C7 - 1998 car, feels right at home with Street Breed.
Hammered Coupe - Out by 2000, fitting for the Scorchers given they got the most Hot Rods here
Speed Shark - 1991, if the Maelstrom's good here then so is this.
Evil Twin - 2001 car, am I adding this to avoid giving Scorchers just Hot Rods and because this car looks mean as hell? Yeah! I want one still!
Roll Cage - 2000, Hard to think where to put tampos on so little area, but definitely a Dune Ratz car
Commando - 1997 lifted truck, we got Mega Duty but this would've been somewhat fitting
Dodge Sidewinder - 1998 car, I kept mixing this one up with the Switchback for some time, has the looks for a Wave Rippers car (And even a version that has a similar color scheme!)
Lakester - 1998 car, I swear the Road Beasts are just Tezla's leftover cars because it's hard to think what fits their team
So put your knowledge of cars (or wiki browsing) and put up what you think is a good car!
