My Tesla Model 3 cost £61,000
I would have lost £12,000 to the HMRC for Corporation Tax, if I hadn't of used the money to buy the Tesla. So I see this as a Discount of sorts. (... and I didn't pay Income Tax or National Insurance to get the car privately).
I did 15,000 miles (14,678 exact) in the last 12 months. It cost me about £180 in electricity (a lot from Solar).
My Petrol Car would have cost me:-
£1.70 per litre (1 x 4.54 = £ 7.72 Uk Gallon)... 32 miles per gallon = (14,678 ÷ 32 = 458.69 UK Gallons) x £ 7.72 = £ 3,541
£ 3,541 - £ 180 = £ 3,361 saving
Keep car for 10 years...
£ 33,610 saving...
£ 61,000 - £ 12,000 - £ 33,000 = £ 16,000 remaining cost
Keep car for 15 years...
£ 50,415 saving...
£ 61,000 - £ 12,000 - £ 50,415 = £ 0
