Even with good intentions, people with bad credit often make costly mistakes on auto loans.
Mistake 1: Buying more car than you need. If you can afford a $20,000 car, don't stretch to $25,000 because the monthly payment only increases by $100. That extra $5,000 at 11.2% APR costs an additional $1,347 in interest over 5 years. Buy a reliable $15,000-$18,000 car instead. Your monthly payment is lower, your interest cost is lower, and you have less to lose if the car is totaled.
Mistake 2: Not shopping around. Getting one pre-approval quote and accepting it costs you money. Three quotes take 2 hours total and can save you $1,000+. This is the highest-return use of your time.
Mistake 3: Extending the loan term to lower the monthly payment. A 72-month loan instead of 60-month lowers your payment by roughly $40/month but adds $2,400+ in interest. If your budget doesn't allow the 60-month payment, the $25,000 car is too expensive. Buy a cheaper car that you can afford on a 48-60 month term.
Mistake 4: Ignoring the loan contract. Read everything before signing. If something doesn't match what was discussed verbally, don't sign. Dealers can't change terms after you leave. If they try (yo-yo sales), you have legal recourse.
Mistake 5: Making voluntary payments above your regular payment without requesting they go to principal. If you send extra money without specifying, some lenders apply it to future payments instead of reducing principal. This doesn't help you pay off the loan faster. Always request extra payments go to principal.
Mistake 6: Taking out loans to pay for add-ons. Gap insurance, extended warranty, and protective coatings are offered at signing. If you can't afford them upfront, you can't afford them financed. Most are overpriced anyway. Decline them.
