Mohair Cover - yes def.
Intercom - installed it, waste of money.
Heated seats - were not available in 2013, would have installed them.
Immobiliser - didn't install it and insurance company insisted I have one!
Door pockets - holds a phone and that's about it.
Quilting - adds a touch of class.
Depending on your height get a smaller diameter wheel with a spacer and move the pedals forward for greater driving comfort. I went Mota-Lita in same leather colour.
