It happens that with our convertible Smart car, the openable roof tends to not close properly over time, causing the partial opening of the hood while driving. This is very unpleasant, especially in winter.

Completely replacing it is a very costly job, even though it would be the definitive solution. What the youtuber suggests in this video is a very economical and easy compromise to implement.

We need to get one or two clamps called "knee clamps" that close with a lever, and we can find them for example on Amazon with the code B08LTH6CHZ at a price of 15.99 euros per pair, with free delivery for Prime customers. The installation requires some drilling, so we need to decide if it's better to use one or both; and then we won't have any more problems.
