Note: costs mentioned below are given in US dollars as a general point of reference — actual prices vary by country, currency, and local market.
Before signing anything: confirm your true budget including insurance, tax/registration, and financing costs (not just the sticker price), get a pre-purchase inspection on any used car (typically $100-$200), pull a vehicle history report for used cars, and compare at least two financing offers (dealer and your own bank/credit union) before agreeing to a rate. New-car buyers should still negotiate on price and check for any manufacturer incentives; used-car buyers should never skip the inspection and history report, even on a car that looks and drives fine.
At a glance
| Step | New car | Used car |
|---|---|---|
| Budget check | Include tax, fees, insurance | Same, plus a repair contingency fund |
| Inspection | Optional (dealer prep) | Independent pre-purchase inspection — essential |
| History check | N/A | Vehicle history report (title, accidents, odometer) |
| Financing | Compare dealer vs outside lender | Same — outside pre-approval strengthens negotiating position |
Step 1: Set a real budget
The purchase price is only part of the cost. Add estimated insurance (get a quote before buying, since it varies hugely by model), registration/road tax, and — if financing — the total interest over the loan term, not just the monthly payment. A common mistake is anchoring to "can I afford the monthly payment" without checking the total cost of ownership over 3-5 years.
Step 2: Research the specific model and trim
- Check reliability data and common problems for that specific model year, not just the nameplate generally
- Compare insurance group/cost across 2-3 trims before deciding — engine size and safety features both affect premiums
- Look up any open recalls for the exact VIN before buying, especially on used cars
New car checklist
- Confirm the out-the-door price in writing, including all fees, before discussing financing
- Check current manufacturer incentives and whether they stack with dealer discounts
- Compare financing: dealer rate vs your bank/credit union pre-approval
- Review the warranty terms and what's covered vs what requires an extended plan
- Inspect the car at delivery for any transport or lot damage before signing final paperwork
Used car checklist
- Pull a vehicle history report using the VIN (checks title status, reported accidents, odometer consistency)
- Get an independent pre-purchase inspection from a mechanic who isn't the seller — typically $100-$200 and can reveal issues a visual check misses
- Verify service records match the mileage and confirm major maintenance (timing belt, transmission service) was done on schedule
- Test drive on both highway and stop-start city roads to catch noises that only show up at certain speeds
- Check for existing liens on the title before transferring payment
| Red flag | What it might indicate |
|---|---|
| Seller won't allow an independent inspection | Possible hidden mechanical or accident history |
| Mismatched paint or panel gaps | Prior accident repair |
| Service records with gaps around major mileage intervals | Deferred maintenance risk |
| Price significantly below market for the model/mileage | Could indicate a salvage title or undisclosed issue — verify history report |
Paperwork to have ready either way
- Proof of insurance (often required before driving off, even temporarily)
- Driver's license and proof of address for registration
- Financing pre-approval letter if using an outside lender
- A written bill of sale or purchase agreement — never rely on a verbal agreement
Never skip a pre-purchase inspection on a used car to save $100-$200 — it's the single highest-value step in this checklist and routinely catches issues that cost far more to fix after purchase.
