Comment: "I am very thankful that I have found your offer. Shipping in scheduled time, without problems. Did all work by myself and everything works great. I've ordered two seals, just in case. Brown one is now in use, car is operated daily. I’m going to install headliner next week because I wanted to inspect it for a while after installation and putting new side windows seals. Good product for good price."

Product: Seal kit for Mercedes 2098001272 hydraulic cylinder (screw-in release valve) - HPU
Product number: MPJ10483
Date of purchase: 11/20/2025
Comment: "From the first call, absolutely wonderful response. Great communication, high-quality product, couple thousand dollars of a job. It turned out to be less than 30 bucks of repair cost. The seals were super easy to install and I had to call twice about the installation instructions. He always picks up the phone and answers all my questions, what a great service. Hopefully I keep buying these convertible tops with issues and fix them with great knowledge and high-quality parts."
