MADNESS Autoworks is located in Signal Hill, CA (an enclave surrounded by the City of Long Beach) and is a facility dedicated to making your favorite ride truly yours by offering a wide line of aftermarket accessories, installation and customizing services.

MADNESS Autoworks was originally known as SMART MADNESS a company that became famous for customizing and accessorizing smart cars.

SMART MADNESS has become the largest provider of smart car parts, accessories and customizing services in North America and now one of the largest globally in just a couple of short years.

We accomplished this goal by providing the very best in products and services at reasonable prices with a personal touch. We treat our customers like family members and do our best to make sure every one of our customers gets the very best treatment possible.

A number of our customers own other cars besides the smart car and continuously ask us if we would also work and or customize their other car due to their positive experience with us. This is how MADNESS Autoworks was born.

Our goal is simple! Provide you, the driver with the widest range of products, servicing and customizing options with friendly service at a very competitive price.

After spending years working on cars and working with many suppliers we thought at times we could do better by designing and manufacturing some products ourselves. We started partnering up with our most trusted manufacturing partners and suppliers, investing in infrastructure, manufacturing equipment and recruiting some of the best talent that could help us design and build superior products and make them available to our fellow drivers.

Our goal is to provide a top quality product that has been tested and used in our own cars and has proven to last and provide a good value for the investment. Whether you are looking for the best value in a set of floor mats, a performance exhaust system, an intake, a roll cage or a carbon fiber part the MADNESS Item is designed to deliver on our promise of bringing a good quality item at a reasonable price. We do not design and build our products to be the cheapest, we design then to be the best value for the money and stand behind them the same way we stand behind our work.

If you ever have a question, need assistance or have a request contact us and we will be glad to help.
