Is salary sacrificing a vehicle worth it?

I would like to purchase an EV.

Friends have suggested salary sacrificing the car to pay for part of it from pretax dollars. They would apparently cover insurance, fuel, maintenance, tyres etc… under the lease agreement.

The thing is - I can’t tell if I’m running the numbers wrong but - I can’t see what the benefit is.

It looks like my out of pocket costs including purchasing at the end of the lease appears to be same as if I bought the car outright and paid for the other things myself?

Shouldn’t my out of pocket be less as part of the cost is covered by pre tax dollars?

Am I missing something?
