We've had several owners report >250K (ptjones, recumpence), but you're soon to enter rarefied territory. You're reliability tracking doesn't show an overall wear out pattern today, but the brakes and plugs won't last forever. I'd renew them before I handed it down. They owe you nothing.
I'll also recommend an upgrade to the HF45 in the Escape. Bigger car, better mileage...
