The man who bought the cheapest McLaren ever sold finally finished rebuilding it, but made a shocking discovery right at the end.

After two years of stress, labor, and money, YouTuber The Inja had finished his $38,500 McLaren project.

But the story wasn’t over yet – there was still one bump in the road left.

Would the Inja be able to overcome it, or would it be back to the drawing board?

The end of the cheapest McLaren project brings forth a new problem

“They say the hardest things in life are the things most worth doing, and this $38,500 McLaren rebuild has been the epitome of a tough project,” The Inja said

We’ll say.

In the two years he’s been working on this project, he’s seen it all.

He’s sourced a bodykit from China, an engine from eBay, and more parts from Temu than we could possibly count here.

There’s been problems along the way, of course, but it’s been a labor of love.

But at long last, this McLaren 650S Spider’s restoration journey is nearing its end.

There was just one thing left to sort out – the airbag light.

You see, it couldn’t be legally registered until the airbag light was cleared.

The only problem with it was that removing the dashboard and replacing the airbag quickly turned into a drawn-out job.

The Inja sourced the used replacement airbag parts from eBay with no guarantee that they would work.

Fortunately, they did, but he still wasn’t out of the woods yet.

The dashboard had sustained a lot of prior damage, so the repair needed to be done carefully.

He used a light application of epoxy, paired with leather repair, to get the job done.

The car powered back up, and the dashboard came to life – but the airbag fault remained.

Could this issue be resolved?

Fortunately, the airbag fault went away after he cleared the codes.

“This was just the push I needed,” The Inja said.

A post-build scan revealed a few lingering issues, including the door module being offline and some sensor problems.

Driving to a specialist, he got the codes cleared and the modules reset.

The major detail here was that the car had done a journey with no leaks or faults detected – a major milestone in its story.

With the build effectively done, The Inja promised to go into details about the costs in a future video.
