What people think vs reality
The sunk cost fallacy - why owners over-invest
"I've had this car for years - it's worth saving no matter the cost."
Every car has a financial point of no return. When repair costs approach or exceed vehicle value, you're not repairing - you're buying the car again.
The sunk cost fallacy: • You've spent £2,000 on repairs last year • You've owned the car for 8 years • You're emotionally attached None of this changes the financial reality: spending £3,500 on a £4,000 car is poor economics. [EM-OBSERVED]
