Lego Arduino car chassis? Or... ?

Question

Arduino

I have such a craft.
Here the Toaster seems to be buggy as before, but there should be a spoiler with this photo attached , but it doesn’t come out.
It's been sitting in a closet for over a year. But Bluetooth control somehow does not give much pleasure, and the design of the machine, as they say, leaves questions behind. I got it from the son of a friend, who sat on a radio-controlled car so that she could roll it, but the poor cart could not bear such a load and the wheel immediately flew off and a couple of cracks appeared in the body. During the time that she collects dust in the closet, a wireless joystick from xbox360 with a usb adapter, and a raspberryPi appeared next to her. The crux of the matter is this. The chassis doesn’t suit me very much, I don’t want to use Tamiya tracks either, I don’t even want to talk about cheap carts from the Chinese with 4 motors. In the desires of a rear-wheel drive chassis and steerable front wheels, you don’t want to spend a lot of money. On YouTube, a shaft of videos about the chassis from Lego, for example, the first one that came across here

upd: I forgot the main question. What Lego sets can I look for for
that purpose?
Or look at more expensive Chinese RC cars? Are there any proven options?

Answer 1

I recommend paying attention to the chassis with rear wheel drive and steerable front wheels from the Fischertechnik "Machines and Drives" set . This is a mechanical constructor, so there will be no problems with modification and expansion of functionality.
The price of the set is 4050 rubles. The store makes a 5% discount for habrausers. habrauser coupon code.

Answer 2

Lego Mindstorm?
