Assembling a radio-controlled toy car based on Arduino. How?

Question

Arduino

Good afternoon. I was interested in the topic with Arduino.
I dug up a broken radio-controlled car at home. The body of the machine itself is intact and I decided to assemble "brains" in it based on Arduino. But since I do not know anything about this area, I ask for advice.
1) Where to buy the Arduino itself?
2) What motors will be compatible with this single boarder? We need a couple of motors to move the machine, and as I understand it, we need a stepper motor to turn the machine.
3) A set of LEDs for headlights.
4) What language is needed for programming?
If possible, please give links to motors, Arduino, and what to read on this topic.
Thanks in advance for your reply.

The main source of information is easyelectronics.com
One arduino is not enough here. You will also need:
-power modules for controlling motors and lights
-power supply
module -Arduin communication module
- these are just brains, and rather frail ones.
The question of the compatibility of the motor with the arduino does not make much sense. The fact is that almost no motor can be connected directly to the arduino, it will burn out.
There will be an intermediary between the arduino and the motor - the power module. Thanks to this, the arduino is actually compatible with any engine.
Regarding "where to buy" - either online stores or electronic component stores. Search by search in your city. In large cities, you can buy everything in one place, but overpaying 1.5-5 times compared to Ali.
How would I make a machine.
For high level brains and communication module I would take something from ESP32 or ESP8266. The first one works with bluetooth and wifi. The second one works only with wi-fi.
An arduino will do as a peripheral controller. But! I would not fence a garden out of a bunch of boards and wires - most likely, it will not fit into the body of the machine, and if it does, it will be very scary.
Therefore, I would place all the components of this design on a specially designed printed circuit board, which then, according to my order, will be made by some Rezonit.
