Im nearly at the stage of ordering the model3 standard range + at £38:500 so judt shy of the £40k tax for premium priced cars , however if i want full autonomy package is 4:3k i think will take the car over the 40k threshold so incurring the 5 year tax ? , or is its value set at base price £38:500 and any extras i put on doesn’t count or does it ? It works out at about £1,000 over the 5 years , or get full autonomy after purchase which is nearly £7k , if the car does go over into £40k then i might just get the long range unit anyway, thoughts please and when can we have a physical test drive in the uk ?
