A customer came to me recently in a tough spot. Her Ford Escape needed about $3,000 in repairs — and there was a coolant leak I hadn't fully diagnosed yet. Trying to be financially smart, she decided to cut her losses and buy a used Nissan Murano instead.
She bought it from a private seller. No inspection. Seemed like a good deal.
The next day, the rear wheel almost came off.
When I got under the car, what I found was one of the worst cases of structural rust I've seen in 21 years of wrenching. The rear subframe — the steel frame that literally holds the rear suspension and wheels to the car — was completely rusted through. Gone. The brake lines running through it were hanging on by a thread.
This wasn't a repair. This was a total loss.
What Is a Pre-Purchase Inspection?
A pre-purchase inspection (PPI) is a thorough mechanical evaluation of a used vehicle performed by an independent mechanic — before you buy it. Not the dealership's tech. Not the seller. Someone who works for you.
A good PPI covers:
Structural integrity — subframe, unibody, frame rails
Brake system — pads, rotors, calipers, brake lines
Suspension components — control arms, tie rods, ball joints, wheel bearings
Engine and transmission — fluid condition, leaks, performance
Cooling system — hoses, radiator, water pump, thermostat
Electrical — lights, sensors, warning codes
Tires — wear patterns, age, condition
Undercarriage — rust, damage, prior repairs
With a professional scan tool, I can also pull any stored or pending diagnostic codes the seller may not have mentioned — or may not even know about.
The Real Cost of Skipping an Inspection
My customer's situation is a perfect example of the math working against you:
Pre-purchase inspection cost: ~$150–$175
What it would have revealed: total loss vehicle
What she paid for the Murano: unknown, but more than $175
Her Ford Escape repairs: $3,000
She traded a fixable car for an unfixable one — trying to save money. A 30-minute inspection would have sent her back to the Escape with full confidence, or at minimum given her the information to walk away.
In the South Sound, private party used car sales are everywhere. Craigslist, Facebook Marketplace, OfferUp — people are moving vehicles fast, and not all of them are disclosing what they know. Washington State has an implied warranty law for licensed dealers, but private party sales are as-is. Once you hand over the cash, the car is yours — problems and all.
Why a Mobile Mechanic Is Ideal for Pre-Purchase Inspections
Here's something most people don't think about: you don't have to take the car to a shop for an inspection. I come to the car.
That means:
Meet the seller at their location — I'll come to them
No need to drive a potentially unsafe vehicle to a shop
Flexible scheduling — I work around your timeline, not a shop's availability
Honest, unbiased assessment — I have no financial interest in selling you anything
As a mobile mechanic serving Tacoma, Puyallup, Spanaway, Federal Way, Lakewood, and the surrounding South Sound area, I can meet you wherever the car is and give you a complete picture before you commit.

The Nissan Murano my customer bought is sitting. It's not safe to drive. And the Ford Escape — the one she traded away her repair budget to avoid fixing — is still out there, probably a much better car than what she ended up with.
A pre-purchase inspection isn't a luxury. It's insurance against making a $5,000 mistake.
