Card 1 — The Goal
🎯 The Goal: Never trust a shiny exterior or a smooth-talking seller. A $40 detail job can hide $4,000 of problems, and the seller knows exactly which angles photograph well. The 5-point inspection takes 20 minutes, requires zero tools beyond a flashlight and a paper towel, and catches the majority of expensive lies before you fall in love with the car. Rule zero: inspect in daylight, on a dry day, with a COLD engine — a pre-warmed engine is a classic tell that it starts badly cold.
Card 2 — Step 1
🛢️ Point 1 & 2 — Under the hood truths. OIL CAP: unscrew it and look underneath. Milky, mayonnaise-like residue = coolant mixing with oil = likely head gasket or worse — walk away, no matter the price (that's a $2,000-4,000 repair pretending to be a bargain). Also pull the oil dipstick: oil should be amber-to-dark brown, not gritty or smelling of gas. TRANSMISSION DIPSTICK (on cars that have one, engine warm and idling for this check): fluid should be pink/red and nearly odorless. Brown-black color or a BURNT smell = a transmission that's been suffering = the single most expensive repair on the car. Sellers can detail an interior in an hour; nobody can detail the inside of a transmission.
Card 3 — Step 2
📏 Point 3 & 4 — The body and tires never lie. PANEL LINES: crouch at each corner and sight down the body — the gaps between panels (door-to-fender, hood-to-bumper) should be even and matching side to side. One wide gap, one tight gap, or paint that's a shade off under sunlight = accident repair they didn't mention (check if doors/hood/trunk all open smoothly too). Magnet trick on suspect panels: body filler isn't magnetic. TIRES: run your palm across each tread. Even wear = healthy; worn INNER or OUTER edges = bad alignment or worn suspension; cupped/scalloped patches = shock absorbers dying; one tire much newer than the other three = ask exactly what happened. Tires are a $150-diagnosis machine that prints its findings in rubber.

🚗 Point 5 + the paper trail. THE TEST DRIVE, windows down, radio OFF: listen for clunks over bumps (suspension), whining that rises with speed (transmission/differential), grinding or squealing brakes, and a steering wheel that pulls or vibrates at highway speed. Watch the temperature gauge the entire drive. Then the documents: 1. VIN check (the plate at the windshield base must match the title — mismatched = stop immediately). 2. Vehicle history report (Carfax/AutoCheck, ~$25 — accidents, flood titles, odometer rollbacks; a seller who won't share the VIN is a seller with a reason). 3. Service records — a folder of oil-change receipts is worth more than any verbal promise. FINAL BOSS RULE: any private-sale car you're serious about gets a pre-purchase inspection at an independent mechanic ($100-200, you pay, your choice of shop). A seller who refuses a PPI has answered your question for free (and see the repair-traps lesson before you pick that mechanic).
Card 5 — The Cheat Sheet
📋 The 5-Point Cheat Sheet: 1. Oil cap: milky residue = walk away. 2. Transmission fluid: burnt smell or brown = walk away. 3. Panel gaps even, paint matching — filler and respray mean undisclosed crash. 4. Tire wear pattern = free alignment/suspension report. 5. Test drive: windows down, radio off, temp gauge watched. 6. VIN match + history report + service records + $150 pre-purchase inspection. Total cost of the checklist: ~$175. Average cost of skipping it: the transmission. Shiny is a detail job. Records are the truth.
