This aston martin supercar has no roof or windshield

I think you may be mistaken! Aston Martin is a luxury sports car manufacturer, and their supercars typically have roofs and windshields to provide protection and comfort for the occupants.

However, I can think of a few possibilities that might fit your description:

1. The Aston Martin Valkyrie: This is a limited-production hypercar that was unveiled in 2016. It has a unique design with a removable roof panel, but it still has a windshield.
2. The Aston Martin DBS Superleggera Volante: This is a convertible version of the DBS Superleggera, which has a retractable hardtop roof. While it doesn't have a traditional windshield, it does have a glass rear screen and side windows.
3. A custom or concept car: It's possible that someone has created a custom or concept car based on an Aston Martin design, but without a roof or windshield. These types of vehicles are often showcased at car shows or online to generate buzz and attention.

If you have any more information or a specific image of the car you're referring to, I'd be happy to try and help you identify it!
