This is a company that makes block car kits that Lego does not make
They are called TheBlockZone. On this website you can get block kits of cars that Lego does not make and can get this at a cheaper price.
The list includes Mclaren P1, Ken Block's hoonicorn mustang, Lancia Stratos, La Ferrari, Datsun 240z, Ferrari F40, AMG G63 6x6, Marauder and many many more. These kit cars feature parts in the 1000s. Like the McLaren P1 is a 3306 piece kit. Some of these build kits are also remote controlled cars - Marauder, Hoonicorn Mustang, the G63 6X6 and more are remote controlled car kits. I reckon these are fun because you can build it then take them for a spin around the house and It makes you feel like a car builder.

I went through some of the list and my favourites include - Gumpert Apollo, McLaren P1, the 2in1 transformer Bumblebee (you build the camaro and then it transforms), Ferrari F1 car (remote control), a Mercedes 300 SL and the Koenigsegg Agera R. There are more but, these will be some of the car I want to start building.

When it comes to price of a kit the Lego Bugatti Chiron kit comes to $350 and a kit like the P1 with the same number of pieces comes to $258.10 (£200). That is a proper restocking of the pantry for at least three days.
