Oh, I see. Your 5000 mile car is petrol. FWIW I think the math still works to get a new EV, because it isn't like you are going to toss away the current car, but sell it to someone used. I think. It's tricky to work through.

Plus, I'm pretty sure EVs will easily last 13+ years, although we have few examples, but EVs are way less complex so they should generally last longer. Even batteries seem to be doing great at 10+ years.
