How to Make Your Car a Convertible in 4 Easy Steps
Convertible simply means you can remove the top. (VOITURE CABRIOLET ALLEMANDE image by Marie-Thérèse GUIHAL from

Transforming a hard top car into a convertible in four steps is an activity that is relatively easy to do. The body of a typical car is mainly a composite of formed steel, aluminium, fibreglass, electrical wiring and plastic. You can cut all of these materials easily with a reciprocating saw fixed with a metal cutting blade. It is important to know the proper operation of a reciprocating saw and the safety concerns involved. Especially important is employing personal safety precautions such as gloves, ear protection, sturdy clothing and appropriate footwear and eyewear.

  1. 1

    Roll down all windows that are designed to be rolled down.

  2. 2

    Cut the top of the car with the reciprocating saw from the left side to the right side at least 3 inches away from the front windshield, where the top of the windshield meets the front of the top of the car.

  3. 3

    Cut horizontally completely through each vertical support for the top and the door windows where the supports meet the door or the body of the car, except for the vertical supports that hold the front windshield. If the support meets the rear window, cut to the bottom edge of the window and stop.

  4. 4

    Remove the top of the car by pulling it straight up with at least one (or more) individual(s) on each side.

Tips and warnings

  • Ensure the car is not running, the ignition is not on, and the vehicle is on stable ground with proper wheel blocking/locking/braking to prevent rolling.
  • Ensure the battery is disconnected and all combustible fuel is removed from vehicle. To make a car into a proper, well designed and safe convertible there are many other steps you should take into consideration. Cuts made with a reciprocating saw are jagged and can cause serious wounds if they are not properly finished smooth by welding and grinding or having a protective covering installed over them. Many cars have tops that are a structural component of the car. Removing the top can have adverse effects on handling and structural integrity, which can pose a major safety hazard and may be illegal.
