If you're asking about the choice of brands and models of cars, I can answer the following: impact on tuning there. And exactly what body parts you'll be set for a particular make and model of the car. When exchanging machines are all external and internal changes are transferred from your current machine to the one you choose. But not all body parts are equally nice on different machines.
But if you're asking about brand choice during the installation of the engine or the transmission, then there's no influence there. Choose the brand that you want.
