Pre-purchase used car inspection





It’s hard to overestimate the importance of a pre-purchase inspection. The risk of buying the wrong car is not just unexpected expensive repairs but compromised safety as well. Non-functional SRS airbag systems, loose bolts in suspension components, rotten frames, and leaking exhaust systems – that’s just a glimpse of what we see every day. To be confident in your next car, order our best-in-class pre-purchase inspection.

Reviews
"Great Inspection saved thous6"

Keith
"Thank you! The inspection was done very quickly and the report was clear and easy to understand!"

Kaila
"Oleg has done a very comprehensive report. The seller reduced his price significantly when I sent over the report. The reduction was more than 10 times the cost of the report, making it very good value for money."

Neil
"Oleg was very prompt and provided a detailed report that saved me money and more importantly time. "

John
"Oleg did an extremely thorough inspection and had it to me within a few hours. He helped me avoid a potential issue that would've cost a lot of money to fix."

Richard
"This experience was better than expected. Oddly enough the check engine light came on after purchase and he came out to see what was missed. It was just that the gas cap wasn’t secure. I appreciate the urgent response and quick through inspection. "

Camri
"I was looking at a 2014 Mercedes C250. Oleg was extremely thorough. The engine had three oil leaks, and the engine control module had recently been cleared, so other things were being hidden from the diagnostics. I will be using them again!"

Customer
"CarAdvisors report was so detailed and informative. It let me know about some very costly issues the car had. The pictures and descriptions were very helpful in making an informed decision about the car. "

Patricia
"Extremely Thorough and detailed. Save us potentially thousands of dollars from a bad purchase. Will use again! Thank you."

SCOTT
"Wow-These guys are incredible. I was buying a car out of state-2017 - BMW X5. I wanted an unbiased opinion for the condition after being told otherwise by the dealership. I ordered and although the report came back with negative findings so I spent money without purchasing, they saved me from making a HUGE mistake. The report is so detailed including undercarriage pictures, every scratch flaw possible you could find. They also drove it and found an issue. I am so thankful I spent the money! Sincerely THANK YOU!! Rich"

Rich
"He was super helpful, he checked all the little deatails of the car and informed me what i was getting into."

Daniel
"I could not be happier with Oleg's service! It was so easy to schedule an inspection of a car that was farther away than I wanted to go (when I wasn't sure it was worth it), and the report was so detailed. He was patient with my questions. The only tip is to confirm his availability via phone in case the website isn't up to date (he responded extremely quickly). Plan to use again!"

Rebecca
"Oleg is awesome. He was available when I scheduled appointment on the same day and showed up right on time. The CarFax showed no accident but he was able to inspect and tell which parts were replaced / repaired. I wouldn’t have been able to spot those without him. Recommended inspection for peace of mind purchasing a used car. "

Lelouch
"The service was fast. I ordered it in the morning and the pre-inspection took place promptly. They did a pretty good job on the visible and engine inspections. The service provided many pictures that highlighted the issues. However, I believe they did not test-drive the cars, and I wasn’t informed about this. It might have been due to the car’s low fuel level, and the fact that I wasn’t present. The day after the pre-inspection, I went to test drive the car and noticed that it leaned towards the right side when driving. Additionally, the car didn’t have an emission test."

Tech Kern
"Oleg was amazing, gave a thorough and in depth inspection of the vehicle, so much so that I already knew I would pass on the vehicle before the test drive. 10/10 am booking again"

Jackson
"Oleg did an amazing job getting the inspection done asap for me. He also took the time to go through the report and explain the things I should consider when chatting with the salesman. Thank you! I strongly recommend Car Advisors! "

Galina
"This was my 2nd time using car advisors. Inspector Oleg is very professional and very focused when performing his task. I would definitely use him again and recommend him to friends and family. "

Customer
"Really impressed by the service and promptness. Highly recommend this option for anyone who is in the market for purchasing a used vehicle. Can’t express enough gratitude thanks again!!!"

Customer
"Fast , efficient and thorough!"

Jeffrey
"Oleg's car inspection SAVED me from buying a used 2018 Jeep Compass from a dealership that had an oil leak and broken fog light which the dealership had no plans of fixing. They claimed to have done a 160 point inspection on the vehicle but Oleg proved otherwise because they would have caught those issues long before I arrived. I'll never buy a used car without having Oleg look at it beforehand, thank you!"

FAQ
?
How qualified are your mechanics?
We are a small team of specialists with master’s degrees, a deep knowledge of car electronics, and many years experience in auto inspection. We don’t hire unknown mechanics from all over the country just to expand our presence in other states.
?
What type of vehicles do you inspect?
We inspect all cars and trucks of any age and price. If a vehicle is a hybrid or is electric, we thoroughly inspect the battery and generator with a professional scan tool to make sure that these expensive parts are in working condition.
?
Can you perform a computer diagnostic for an older vehicle with a non-standard diagnostic connector(not OBD2)?
Yes, we have special connectors for a wide variety of older vehicles. So even if it doesn't have a carburetor we can perform a computer diagnostic.
?
What types of payments do you accept?
You may pay with card (debit or credit), from your account, or by cash or check after the inspection if you decide to see it in person.
?
Can I cancel an inspection that has already been ordered and scheduled?
Yes, you can cancel an inspection at any time without charge. However, it's preferred that you provide at least 1 hour before the scheduled inspection time.
?
Do you inspect vehicles on a lift?
It depends on the seller. If the seller has the facility to lift the vehicle (for example, if the seller is an auto dealer with a shop) then our specialist would inspect it on the lift. In most cases however, there is a necessity for a lift only if the test drive revealed issues with the drivetrain or suspension, and to determine the source of the problem and if it's ok to lift the car. Otherwise, inspection without a lift won't compromise the quality of the inspection itself.
