Buy With Your Eyes Open
A used car can look perfect in the photos and still hide a cracked control arm, a leaking transmission, or a battery that's quietly losing range. A Pre-Purchase Inspection in San Bruno, CA puts the car on our lift and through our scan tools before you hand over any money, so you know exactly what you're buying. We tell you what we find in plain English, with photos, and you decide from there.
When a Pre-Purchase Inspection makes sense
If you're about to spend real money on a car you haven't owned, an inspection is worth it. Here are the situations where it matters most.
- Buying from a private seller. There's no dealer warranty and no lot to go back to. Once the cash changes hands, the problems are yours.
- Buying a Tesla or Porsche used. These cars carry expensive systems — HV batteries, PDK transmissions, air suspension — and a quiet fault can cost more than the discount you negotiated. We check them with the same software the dealer uses.
- The deal feels rushed. If a seller won't let the car leave for an hour or pushes you to sign today, that's exactly when an independent set of eyes protects you.
- The price seems too good. A low number sometimes reflects a problem the seller knows about and you don't. We find out which it is.
- High mileage or an older luxury car. Wear items add up. Knowing what's due — brakes, struts, fluids, tires — lets you budget or renegotiate before you own it.
- You're buying sight-unseen or from out of the area. If you can't be there yourself, we can be your eyes at the car.
If you're nodding along to any of these, book the inspection before you commit.
What the work involves
A Pre-Purchase Inspection is a focused, head-to-toe check of a car's condition and history as told by its data. We combine a hands-on visual inspection with electronic testing, then give you the whole picture.
The electronic side. We connect our scan tools and read the car's stored trouble codes and live data. For a Tesla, we use the official Tesla diagnostic software we license. For a Porsche, we use PIWIS 4. For everything else, our Snap-on and Matco bi-directional scan tools read codes and live data and let us command components on and off to confirm they actually work — not just that no warning light is showing. A cleared code or a seller who unplugged a light won't fool a proper scan.
The physical side. On the lift we look at the suspension and steering — control arms, ball joints, tie rods, shocks and struts — along with the brakes, tires, fluids, belts, hoses and signs of leaks. We check for prior collision repair, rust, and any harness damage, including chewed wiring from rodents. We look over the A/C and the charging system.
The trade-offs. A basic code-and-visual check tells you whether the car is hiding obvious trouble and is fast. A deeper diagnostic — more time on the lift, more component testing — is the better call on a high-value car, a model with known weak points, or any car where the first look raises a question. More thorough costs more time, but on a Tesla or Porsche that depth often pays for itself in one finding. We'll tell you which level fits the car you're looking at.
Why choose Express Auto Repair
- We built the shop around Tesla and Porsche. The official Tesla diagnostic software and PIWIS 4 are already here, so a used EV or 911 gets inspected with the real tools instead of a guess.
- You see everything we see. We text you the findings with photos before you make a decision. Nothing is hidden in jargon, and nothing gets charged that you didn't approve.
- Independent and honest about the car. We're not selling you the vehicle, so we have no reason to talk it up or talk it down. We report the condition and let the data speak.
- OEM parts and independent labor rates. If the inspection turns into a repair after you buy, you get OEM parts without the dealer pricing.
Our Pre-Purchase Inspection process
- 1Tell us about the car. Call us at (650) 588-9199 with the year, make, model and where it is. We'll help you arrange time with the seller.
- 2Bring it in, or we come to you. Drop the car at the shop on San Mateo Ave, or within about three miles we can pick it up and bring it back to the same spot.
- 3Scan and read the data. We pull stored codes and live data with the right software for the make and test components we can command.
- 4Inspect on the lift. We go over suspension, brakes, tires, fluids, leaks, prior repair and wiring by hand.
- 5We text you the findings. Photos, plain-English notes, and what each issue means for cost and safety.
- 6You decide. Buy it, walk away, or go back to the seller with real leverage. If you buy and want work done, we give you an estimate for approval by text first.
What affects the cost and how to get a price
The price of a Pre-Purchase Inspection depends on the car and the depth it needs. A straightforward sedan with a quick code scan and visual check takes less time than a Porsche that needs PIWIS 4 diagnostics or a Tesla that calls for a full battery and charging review. Harder-to-reach components, a history that raises questions, or a request to test specific systems all add time, and time is what drives the number. Where the car is located matters too, since pick-up within our range is free and a vehicle farther out takes more coordination.
The honest answer is that we quote per car. Call us at (650) 588-9199 with the details and we'll give you a clear price before anything starts — no surprises, and no work beyond what you approve.
After the inspection — buying smart and keeping it healthy
If the report comes back clean, you can buy with confidence and start fresh with a baseline you can trust. If we found wear items — brakes near the end, a weeping seal, tires with little tread left — you've got a list to negotiate with and a plan for what to budget first.
Once the car is yours, the easiest way to protect it is to keep up with the basics: oil changes on schedule, brake and fluid service when they're due, and a scan at the first sign of a warning light rather than after. We keep your inspection on file, so when you come back for service we already know the car's starting condition and can watch the things we flagged. Catching a small issue early is almost always cheaper than waiting for it to fail.
