This review reflects only my firsthand experience and the documented facts surrounding my transaction with JS Autohaus. I have timestamps, texts, Porsche inspection reports, and witnesses supporting every detail below.
I sold my 2018 Porsche Boxster S to JS Autohaus, and my experience was nowhere near the professionalism and transparency they present online. After they arranged transport, communication became unreliable. Several of my calls went unanswered--including one day where I called five times--and many texts were answered hours or days later. I even had to rely on a Tile hidden in the car to track movement because updates were inconsistent.
Before the car was even shipped, there were avoidable delays because their acquisition specialist, Matt, repeatedly sent my sale documents to the wrong (misspelled) email address, even after I told him I hadn't received anything. Instead of verifying the spelling or copying and pasting the correct email, he continued sending documents to the wrong one, which wasted two days.
When the car arrived in New Jersey, JS Autohaus claimed it "might have water damage" based solely on an odor. The car lived in a garage in Las Vegas--one of the driest climates in the country--with zero moisture issues in my four years of ownership. Despite having no contractual obligation to allow any third-party inspection before payment, I agreed because I had nothing to hide.
Instead of completing their standard in-house intake, JS Autohaus insisted on taking the car to a third-party Porsche dealership, which delayed payment by two additional days. Matt called me directly to ask if I was okay with waiting until Friday's Porsche appointment for payment. Again, I agreed because I had nothing to hide. If I had been hiding a defect, I certainly wouldn't have voluntarily approved a third-party manufacturer inspection before getting paid.
The Porsche inspection found no mechanical issues, no cosmetic issues, and no water damage. It confirmed the worn tires and brake sensors I had already disclosed up front. The only new issue was a failed Bose amplifier--an electronic control module that did not fail in my possession and is unrelated to any mechanical systems.
Despite this, Matt repeatedly attempted to classify the amplifier as an "undisclosed mechanical defect" covered under their contract. The amp is a MOST-Bus electronic control unit with no moving parts or mechanical linkage, something even the GM, Jean Saliba, eventually admitted on the phone when he said: "Yeah, this is an electronic part." Yet Matt later texted that "something mechanical caused the amp to fail," which contradicted Porsche's inspection, contradicted the GM's admission, and contradicted basic automotive principles.
JS Autohaus then pressured me to cover the entire $2,600 replacement cost. I refused. I still offered $1,000 as a goodwill gesture--despite having zero contractual or factual obligation to do so--but they rejected it. Their "compromise" was that I should pay the entire $1,700 part while they paid labor, which was disproportionate and unsupported by the contract.
When I said they could return the car if they didn't want to honor the price, I was told I would have to pay return shipping. My understanding of UCC standards is that once the buyer accepts delivery, moves the car, and initiates inspection, the seller is not responsible for return shipping unless they breached the contract--which I did not. Porsche confirmed I disclosed everything accurately.
During the call with GM Jean Saliba, I clearly stated how unhappy I was with how this was handled. Jean said they were unhappy too. When I repeated that the amplifier is electronic, wasn't defective in my possession, and isn't covered under their "undisclosed mechanical defect" clause, he admitted it was electronic--then told me I "should be paying more," which made no sense given the inspection results. When my boyfriend pointed out that the issue didn't exist at pickup and that their behavior didn't match their public persona, Jean talked over him. When my boyfriend mentioned their videos and branding, Jean hung up on us.
After all the delays, shifting explanations, contract twisting, and pressure, I ended up taking a $1,500 loss from the originally agreed price simply to end the ordeal. This loss was entirely due to their misclassification of an electronic component, refusal to honor the contract as written, internal communication failures, and unwillingness to accept responsibility for an issue that arose after transport, during their chain of custody.
Nothing about this experience aligned with the fairness, integrity, or customer-first values JS Autohaus promotes online. Instead, I experienced poor communication, sloppy handling of paperwork, misrepresentation of technical facts, inconsistent explanations, pressure tactics, and unprofessional behavior from management.
