DIY Engine Fluid Checklist for Used Cars

If you only have time for one under-the-hood check before buying a used car, fluids are one of the best places to start. Fluid condition tells a story: overheating, skipped maintenance, internal wear, leaks, or a seller trying to hide a problem with fresh top-offs. I’ll walk you through what to...

How to Get a Pre-Purchase Inspection (PPI) on a Used Car

If you take only one smart step before buying a used car, make it a pre-purchase inspection, or PPI. I’ve been the guy on the lift delivering the bad news after someone already bought the car. A PPI flips that script. It turns an emotional purchase into a fact-based decision, and it usually costs...

16 Questions to Ask Before and After a Test Drive

Most “bad used car” stories I’ve seen did not happen because the buyer skipped the test drive. They happened because nobody asked the right questions around the test drive . A seller can talk fast, a car can feel smooth for 15 minutes, and you can still end up with a money pit. Here are the 16...

Inspecting a Used EV or Hybrid

I love EVs and hybrids for used buyers, when they are healthy. They can be quiet, cheap to run, and in the right model and year, impressively reliable. But the inspection priorities are different from a gas car. You are not just listening for a rough idle. You are trying to avoid a high-voltage...

How to Check Under the Hood of a Used Car

Opening the hood can feel like staring into a bowl of spaghetti, especially on a modern car. The good news is you do not need to be a mechanic to catch the big, expensive problems. In a few minutes, you can spot signs of severe neglect, overheating, bad maintenance, or a seller trying to hide...

How to Use an OBD2 Scanner When Buying a Used Car

An OBD2 scanner is one of the cheapest pieces of “insurance” you can bring to a used car test drive. In about five minutes, it can uncover a lot: stored trouble codes, pending issues, and clues that a seller recently cleared codes to make the dash look clean. I love a good test drive and a careful...

7 Hidden Maintenance Red Flags to Notice on a Used Car Test Drive

Most used cars don’t scream “I’m a problem.” They whisper it. A faint whine at 45 mph. A hot, sweet smell after a highway merge or longer acceleration. A steering wheel that trembles just enough for you to second-guess yourself. When I did pre-purchase inspections , the buyers who avoided the worst...

Test Driving at a Dealership vs. Private Seller: What to Expect

Test drives are where the truth shows up. But the experience can feel totally different depending on whether you’re driving a car from a dealership lot or meeting a private seller in a grocery store parking lot. I’ve done a lot of pre-purchase inspections, and I can tell you this: the best test...

DIY Used Car Inspection vs. Professional PPI

If you have ever watched a friend buy a used car that turned into a money pit, you already understand the stakes. The hard part is deciding how deep to go before you hand over your cash. Do you do your own inspection in the driveway and call it good, or do you pay an independent shop for a...

Used Car Test Drive Checklist

I’ve inspected a lot of used cars over the years, and I can tell you this: many expensive problems only show themselves when the car is cold, under load, or trying to stop from speed. A quick spin around the block with the radio on will miss the stuff that empties your wallet later. This checklist...

How to Test a Used Car’s Transmission

If an engine is the heart of a car, the transmission is the part that makes that heart usable. And when a transmission is failing, the repair bill can be brutal. The tough part is that many transmission problems show up as little quirks at first: a soft flare between gears, a delayed engagement, a...

Spotting Hidden Accident Damage and Rust

After years of inspecting used cars for people who just wanted something safe and dependable, I can tell you this: the worst accident damage and rust are rarely obvious. It is the subtle stuff. A slightly different shade of paint. A door gap that tightens up at one corner. A “clean” undercarriage...

How to Arrange a Pre-Purchase Inspection (PPI)

After years of inspecting used cars for buyers, I can tell you this: a pre-purchase inspection (PPI) is the cheapest “insurance policy” you can buy in the used car world. It is a professional, unbiased look at a vehicle before money changes hands. A good PPI can catch the stuff that doesn’t show up...

7 Hidden Red Flags During a Used Car Test Drive

I have watched a lot of good people fall in love with a used car that “drove great,” only to come back a week later with a flashing warning light and a sinking feeling. The tricky part is that many serious problems do not announce themselves with a loud bang. They show up as little quirks that are...
