Welcome! With that one picture it’s gonna be tough for anyone to toss an educated price to you. It looks like it’s missing trim (headlight and headlight trim at a minimum).
Best to unbury the Scamp and take a bunch of photos. Looks like it’s gonna take a while to get to the Scamp given how close other two cars are parked beside it.
Do any of the cars run? Could be a day job hauling the cars out.
