This US man bought a cheap Porsche Cayenne Turbo, betting that its mysterious engine noise wasn’t a big deal.
YouTuber LegitStreetCars took a chance on this car, despite an unexplained noise.
He admitted his purchase could go either way – be ‘awesome’ or a ‘complete disaster’.
Only a more thorough inspection would reveal the truth.

Buying a car at auction can often be a gamble.
A car with an extensive history behind it can often be hiding issues, as was the case with this Toyota Camry TRD bought in New Mexico.
However, buying these vehicles can often pay off too.
One guy over in North Carolina secured his dream car on an eBay auction after waiting 34 long years.

Down in Florida, a junk Corvette turned out to be a time capsule.
It’s a gamble, but some people are willing to take it.
LegitStreetCars was one such person, as he purchased a Porsche Cayenne Turbo on auction.
As he was looking the car over, he was quite happy with its appearance.
However, he had been told that there was an issue with an engine leak.

And as starting up the Porsche produced a troubling noise, his concerns only grew.
“It’s definitely a tapping noise… is that a rod knock?” he said.
“It’s definitely running really rough and the check engine light is on.”
This is where buyers remorse might be setting in for some – but hope was not lost yet.
Even getting it over to the gas station was a struggle.
It was on LegitStreetCars to get into the nitty gritty workings of the engine.
And to say it was a stressful process would be putting it mildly.

“I’m telling you guys, working with German cars takes years off your life,” he said.
“I just got three more grey hairs.”
Closer inspection found that it was cylinder seven that was misfiring.
The complicated name of the diagnosis did make him reflect on the increasing popularity of electric cars.
“This is why electric vehicles are going to take over,” he commented.
“Look at the complexity.”

Not only is it complicated, it’s costly – fixing this engine could cost him up to $20,000.
“This is the definition of mechanically totaled,” LegitStreetCars said.
At the end of the video, the engine was unfortunately still a work in progress, with the host weighing up his options on what to do next.
