A person with $1 million in a 401(k) who drives a 15-year-old car can look like a contradiction. The retirement account suggests serious wealth, while the aging vehicle suggests someone who refuses to spend money.
Neither conclusion necessarily fits. The car might represent careful spending, simple preferences, or nothing more complicated than a vehicle that still works. The 401(k) also tells only part of the financial story. Someone can have a seven-figure retirement account and still face mortgage payments, taxes, insurance, health costs, family expenses, or other financial obligations.
