The base spec Tiguan petrol was just under the insurance bracket for under 25s I believe.
When I got our Tiguan the dealer emailed me a welcome to your new Tiguan brochure with details of spec and all the extras.
Before I even did anything I got the dealer to show me everything and how it worked, then both they and me are covered.
I wouldn’t enter my pin until you try everything and thoroughly inspect the car. Bring someone with you so you don’t just get doe eyed at the site of a shiny new car.
