Pre-purchase car inspection in Dallas for any make

What do North Texas used cars hide most often?

Flood cars. Spring storms and flash flooding put cars under water every year, and some of them are dried, cleaned and sold months later, sometimes with a title from another state. The signs are silt in the seat tracks and under the carpet, rust on the seat bolts and the seat belt anchors, a musty smell the air freshener cannot cover, corrosion on connectors low in the car and a water line in the trunk. The inspection looks for every one of them.

Hail cars. A hailstorm can total a car cosmetically while leaving it mechanically fine, and a hail car repaired well can be a bargain; a hail car repaired badly, or sold with a rebuilt title at a clean-title price, is not. The report says which.

Collision repair. Paint depth and bolt heads tell the story, and the lift shows whether the frame rails and the suspension mounts were pulled straight or left bent. Then the ordinary findings: a CVT that is on its way out, brakes near the limit, tires with plenty of tread that are six years old, an A/C that cools in the shade and not on the road, and oil leaks on a high-mileage engine that were cleaned for the listing.

When is the extended inspection with compression and leak-down worth it?

On a high-mileage engine, a turbocharged engine, an engine with a known weak point, or any car where the price depends on the engine being healthy, the extended inspection at $249–$349 adds a compression test and a leak-down test on every cylinder. Compression shows whether the cylinders are even; leak-down shows where any loss is going, past the rings, the valves or a head gasket. Together they catch the engine that runs well on a test drive and burns a quart every 600 miles.

It is also the right choice for a truck that has towed, for a car that was imported from a colder state with a rust history, and for sports cars and performance models. For a four-year-old Corolla with service records, the standard inspection is enough.

On diesel pickups, the extended inspection includes the emissions system and the DEF system, which are the expensive failures on those trucks.

How do you use the report with a private seller or a dealer?

The report lists every finding with a photo, a severity (now, soon, watch) and the range from the shop's own price table for fixing it. With a private seller that is the negotiation: brakes at $249–$699 an axle, a CVT service at $189–$299, a battery at $179–$399 are concrete numbers to take off the asking price, and a flood suspect or a bent frame is a reason to walk away whatever the price.

With a dealer, federal rules require a Buyers Guide on the window that says whether the car is sold as is or with a warranty, and as is means exactly that. The report tells you what you would be buying and what you should ask the dealer to fix before you sign. If a dealer refuses to let the car be inspected off its lot, that is itself a finding.

The report is yours whether or not you buy the car, and it is written so the next shop can read it too.

How does the inspection work when the car is at a seller's location?

The inspection is done at the shop, because the lift, the scan tools and the test equipment are here; the seller or the dealer brings the car in or allows you to drive it in. Most sellers agree when they are told it is a two-hour visit at a fixed price and that the car comes back the same day. The shop does not travel to the car.

Book with the year, make, model, mileage and the listing if there is one, so the known weak points for that engine and transmission are on the checklist before the car arrives. If the seller refuses an inspection, the shop can only say what that usually means.

What does the inspection cost and what moves the price?

Standard inspection with written report and photos $129–$229; extended inspection with compression and leak-down $249–$349. Inside the range the figure moves with the vehicle: a diesel or a European car takes longer to scan and to inspect underneath than a compact sedan, and a lifted truck or a modified car takes longer still.

The fee is for the inspection and the report, not for repairs, and no repair is done to the car without the owner's approval. Any repair you later book here for a car you bought is covered for 2 years parts and 2 years labor, up to 24,000 miles, nationwide.
