Welcome
@ThOmSn . The only advice I can give you is don't compare Blender to other 3D package you might've used before, just "go with the flow". You'll soon start to really appreciate its ergonomics and ease of use. It happened to me

. I am not an expert either, but I can manage it decent enough now. I've started using it because of Assetto Corsa

.
There are tons of tutorials out there, here are a few useful sites:

Don't hesitate to create a thread in the car model section, and keep us informed. If you get stuck, or have questions, share them there. "We" 'll try to help
