I'm keen on getting a black facelift 2017 FR with 18" performance alloy wheels and the one I saw is registered in March 2017 so it is £30 tax instead of £145 however it doesn't have the convenience pack (auto lights, wipers and auto dimming rear view mirror) so I'm wondering how useful is the pack and is it worth around £400-500 more for it which I saw in another colour and the trade-off of higher tax?
