I'm an admirer of Tesla and enjoy a P85D. I'm curious about what Tesla will do to new car sales (across the industry) as the sold fleet ages. Traditional car companies intentionally balance their costs against consumers proclivity to buy new cars in the 4-8 year range. As such, they'll spend $10 less on a part that goes to 100K miles instead of 500K. These Teslas are going to last longer that people realize and won't age out as early as other cars. How will that impact new car sales?
