Inspect before you pay

How to inspect like you mean it

Most private-party buyers spend twenty minutes kicking tires and checking whether the radio works. That is how you end up with a car that needs $2,400 in deferred maintenance you did not see coming.

The fifteen-minute walkaround

Before you even open the door, walk the full perimeter slowly. Look for panel gaps that change width, paint that does not match between doors, and overspray on rubber trim. These suggest prior collision repair. Check tire tread depth with a quarter: insert it into the groove. If you see the top of Washington's head, the tires are near replacement. Uneven wear across the tread hints at alignment or suspension issues.

Under the hood: what matters most

With the engine cold, pull the oil dipstick. The oil should be amber to dark brown, not milky or gritty. Milky oil means coolant contamination, usually a blown head gasket. Check the coolant in the reservoir: it should be clean, not rusty or oily. Look at the battery terminals for corrosion, and ask when the battery was last replaced. Most last four to five years.

The test drive you actually need

Drive at least ten miles on varied roads: highway, stop-and-go, and a bumpy side street. At highway speed, let go of the wheel briefly on a straight section. If the car drifts, check alignment. Brake firmly from 40 mph: pulsing in the pedal means warped rotors. Turn the wheel lock to lock while parked: clunking suggests worn CV joints or rack issues. Run the heater and AC full blast to verify both work.

Common mistakes that cost buyers

• Trusting a clean Carfax as gospel. Not all accidents get reported.
• Skipping the cold start. A warm engine hides startup problems.
• Not checking all four tire dates. Three new tires and one original means recent damage or neglect.
• Ignoring the spare tire well. Water or rust there signals leaks or past flooding.
• Negotiating before inspecting. Always inspect first, or you anchor yourself to a number.

When to walk away, no exceptions

Sellers who refuse a test drive, have no title in hand, or pressure you with "someone else is coming tonight" are not worth the risk. A salvage title without full documentation of the repair is a permanent red flag. Smoke from the tailpipe, knocking engine sounds, or transmission that flares between gears mean repairs that often exceed the car's value.

About repair cost estimates

The ranges in this scorecard come from national average labor rates and common aftermarket parts pricing. Your local independent shop may beat these numbers; dealerships usually exceed them. Use the estimates as negotiation anchors, not promises. For major engine or transmission work, get a written estimate from a shop before finalizing the purchase.
