Replacement of Convertible Tops

The convertible top on a modern car is a complicated, sophisticated, sequential system where everything must work in order or the whole system shuts down. For instance, a Mercedes Benz 500 SL roadster has eleven hydraulically operated latches that must work in sequence so that the top will open and close properly. Over time, components of the system wear out or break. If you notice drips on your garage floor and sluggish top operation, a top lift cylinder may be leaking and will need to be replaced.

The old-school cars (20’s-80’s) are less complex but have other issues; typically worn-out weather strips, rotten wood frame components, rust, bent and broken latches, bolts and framework. We can address all of these issues, including painting your framework if this is a show car.

Replacement of a car convertible top is always a many-step, detailed, sometimes tricky process. Installation times in some models can run as high as 20 hours. Because it is complicated, quoting a price without inspection is simply a guess. We use a 10 pt. checklist including a water-test to identify which parts you may or may not need for a proper top restoration.

We can inspect your top while you wait at no cost when you stop in. You will have choices including fabric, color and level of restoration. We use only high-quality tops and properly install each top to manufacturer specification. We guarantee our convertible top workmanship 100% for life and replacement tops for their service lives.

This guarantee is based on over 36 years experience installing hundreds of tops on a wide variety of car makes and models. We are the convertible top installer of choice for dealers of high-end brands like Mercedes, BMW, Audi, Porsche and Corvette.
