You got yourself a steal, and with a car that works for you.
You would pay twice that on a motability car
My buddy was very impressed with my EV and its running costs.
He is due to renew the car he uses for work in 6 months. I suggested looking at a Model 3 they can be picked up for £17k, or by next year the Ioniq 5 will drop to a similar price at renewal. His running costs for his Golf gdi are high, fuel and servicing. He spends £2.5K/ year on fuel. I pointed out his fuel costs with an EV will be £250/year.
You get something that works for you. But that a good deal outwith Motability.
