Only option I regret not getting was the heated front screen
I made that mistake.
I specced it, but when the dealer sent me the final order to check & confirm he'd left the option off and I didn't spot it was missing. By the time I'd realised it was missing the spec had been locked. He apologised, but in fairness it was both our mistake.
My car lives outside, so I thought i'd really miss it, but truth be told a jug of tepid tap water has done the trick when needed. The trick is not to breath in the car when you first open it up to start.
