I purchased this item used, so I don't know the compatible chassis. It's a pre-painted 1/10 scale body with a square hole in the front window, possibly for refueling (see photo 3). This is a rare blue Mercedes-Benz body with adult-themed photos and a rear wing. Please refrain from purchasing if you are concerned about minor cracks or dirt, as this is a junk item. - Brand: MOBIL 1 - Model Name: Mercedes-Benz - Color: Blue - Design: Adult Sexy Design - Features: Rear Wing Thank you for looking.
