Yes, you can indeed replace the steering wheel. In fact, one of the most popular aftermarket modifications and personalization touches that car enthusiasts typically do is to have their steering wheels replaced. Factory steering wheels are often quite bulky and complicated, not with all their buttons, switches, and whatnot. Furthermore, they don't typically feel that great to hold, especially for more budget-oriented cars. Whereas, you can easily swap them out for a simple aftermarket wheel, which is more ergonomic, in addition to being comfier to grasp onto. And, they can ensure a better fit, which is especially crucial if you're swapping it into a sports car.
