New vs Used — Which Should You Buy in 2026?

The first decision every buyer faces is new versus used. Both have strong arguments in 2026 — used car prices have normalized after the pandemic spike but remain elevated, while new car incentives and financing offers have improved significantly.

💡 Best Value Sweet Spot: A certified pre-owned (CPO) vehicle that is 2–3 years old with 25,000–40,000 miles offers the best of both worlds — most depreciation already absorbed, manufacturer-backed warranty, and significantly lower price than new.
Before You Shop

How To Buy a Car — Step by Step

  1. Set your total budget — not just monthly payment. Dealers love to focus on monthly payment to obscure the total cost. Decide the maximum total price you'll pay before stepping foot on a lot. A good rule: total car payment should not exceed 15% of your monthly take-home pay.
  2. Get pre-approved financing before visiting a dealer. Apply at your bank, credit union, or online lenders before you shop. Having a pre-approval gives you negotiating leverage and protects you from dealer financing markups. Credit unions typically offer the lowest auto loan rates.
  3. Research the true market value. Use Edmunds True Market Value, KBB, and CarGurus to understand what the car is actually selling for in your market. Never negotiate from the sticker price — negotiate from actual transaction data.
  4. Get quotes from multiple dealers. Email 5–10 dealers with a specific request: "I'm looking for [Year/Make/Model/Trim] and will make a purchase decision this week. What is your best out-the-door price?" Create competition between dealerships.
  5. Negotiate out-the-door price only. The only number that matters is the total out-the-door price — vehicle price plus all fees and taxes. Never negotiate monthly payment — dealers can manipulate payment by extending the loan term.
  6. Review add-ons carefully in the finance office. Extended warranties, paint protection, fabric protection, and gap insurance are major profit centers for dealers. Research each one independently and only accept what provides genuine value at a fair price.
  7. Get everything in writing before signing. Verbal promises mean nothing. Ensure every agreed-upon term — price, trade-in value, financing rate, add-ons — is reflected in the contract before you sign.
  8. Don't rush. Dealers use urgency tactics ("this deal is only good today," "another buyer is interested"). The best deals are made by buyers willing to walk away. There is almost always another car.
Financing

Car Loan Rates and Financing in 2026

Auto loan rates in 2026 vary significantly based on credit score, loan term, and whether you're buying new or used. Understanding financing is critical to calculating the true cost of ownership.

Credit ScoreNew Car Rate (avg)Used Car Rate (avg)
Excellent (720+)5.5%–7.0%7.0%–9.0%
Good (680–719)7.0%–9.5%9.0%–12.0%
Fair (640–679)9.5%–13.0%12.0%–16.0%
Poor (580–639)13.0%–18.0%16.0%–21.0%
Very Poor (below 580)18.0%–25.0%+20.0%–29.0%+
⚠️ The Loan Term Trap: A 72 or 84-month loan has a lower monthly payment but costs thousands more in interest and puts you at risk of being underwater — owing more than the car is worth. Try to keep loan terms to 60 months or less.

FAQ

Car Buying FAQ

What is the best time of year to buy a car?

The best times are the last few days of a month (dealers pushing to hit monthly quotas), the end of a quarter (March, June, September, December), and the end of the year (December when dealers clear inventory for new model years). Monday through Thursday visits tend to yield better deals than weekends when dealers are busiest. Holidays like Memorial Day and Labor Day often have manufacturer incentive programs but showrooms are busy — negotiate everything via email first.

Should I tell the dealer I'm paying cash?

Counterintuitively, no — not initially. Dealers make profit from financing arrangements, so revealing you're paying cash can cause them to become less flexible on the vehicle price. Negotiate the vehicle price first, then reveal your payment method. If you have pre-approved financing, compare the dealer's financing offer against your pre-approval before committing to either.

How much should I put down on a car?

Aim for at least 20% down on a new car and 10% on a used car. A larger down payment reduces your monthly payment, total interest paid, and the risk of being underwater on the loan (owing more than the car is worth). If putting 20% down is not possible, a minimum of 10–15% is recommended to stay ahead of depreciation, especially on a new vehicle.

Is it worth buying an extended warranty?

Manufacturer-backed extended warranties (CPO warranties) can be worth it for luxury or reliability-questioned vehicles. Third-party warranties from dealerships are almost always overpriced and have restrictive fine print. If you want an extended warranty, price it from the manufacturer directly rather than through the dealership finance office where markups are significant. For highly reliable vehicles (Toyota, Honda, Mazda) an extended warranty is rarely cost-effective.
