Okay, I want to add off-road accessories, a bull bar, and a light bar to my 2018 Land Rover Discovery Sport. I have two questions: first, am I stupid, and second, if not, what information should I include? Just in need of some ideas. Can I still get roof rails installed if I wish to put anything on the roof but do not currently have them? I really don't know where to begin, so thank you everyone!
