FORMULA STEERING WHEELS
Scalextric has “Detail Parts” and “Accessory Packs” for $3usd that contain a F1 style wheel with painted buttons (incl in the pack are a drivers head and mirrors). Electric Dreams have about 6 packs, PSR has about a dozen. They match Scaley modern F1 liveries, so you should find one with a color compatible with your car.

Carrera F1 Bodies have a more accurate Square Steering Wheel:
These are not painted and are not offered in repair part kits; they have to be harvested from old bodies. Some are on shafts
Others have small 90deg hook. You have to pop out the driver/seat partially to pop out the wheel assembly.
"... get on your bad motor scooter and ride!"
