You can buy a model 3 that goes 0-60 in 3.1 seconds, right now, on their website under 40k after tax rebate. Go look. Under existing inventory. All prices exclude the 7500 credit.
Are you claiming GM never made a lemon? That no car, ever, in the history of their company, was sold with a bad motor?
And stop it. You’re comparing the cost of a new battery now vs what the cost of a used battery will be in 8 years. Claiming that technology doesn’t get cheaper is absurd. You can buy a used Nissan leaf battery for $3,700.
