Car
The radical car and the kanji car are exactly the same.
Make sure you study your radicals... though don't do it while driving.
しゃ
くるま
None
When we need to remember the reading しゃ, we use "shaman". There's a car. It's the nicest car you've ever seen. Exquisite, beautiful. Wouldn't you be surprised to learn it belongs to a shaman (しゃ)? Well it does. This shaman charges a premium for his shaman services so he can afford fancy cars like this.
The more fantastic you make this car, the better. Also, feel the surprise of a shaman getting out of this car. What a cool dude that shaman is.
