Chevrolet mechanic reveals why you should never buy a car built on this day

A Chevrolet mechanic has issued a warning about buying cars built on certain days of the week.

Content creator Shelby Master says in a TikTok video that the quality of a car depends on the day of the week it was built - and gives a theory as to why.

'You want to see the difference between a Z06 built on a Friday and a Z06 built on a Tuesday? Look at that,' he said as he showed viewers two examples of the sports car.

The one made on a Friday - the orange one in the images below - has a a noticeable bump between the front bumper panel and the front driver's side.

But the other example, a red model made on a Tuesday, has clean lines with no protrusions.

Master suggests that the badly assembled car was made on a Friday because workers were checked out and ready to hurry off to enjoy their weekend.

Whereas the car made on a Tuesday when workers were more alert and engrossed in their work produced less flaws.

Crucially, on a Tuesday, staff have gotten over their hangovers that they might still have on a Monday, which is another day where quality is lower.

Some online were still convinced by the theory, with one user commenting, 'never buy a car built on a Monday morning or a Friday afternoon. Truth.'

'I know that Friday work. I see it quite often,' another wrote under Master video.

But car publication Jalopnik says the idea of cars being better or worse depending on which day of the week they are constructed is a myth.

'The complete manufacturing process for a modern car takes more than a single day (though final assembly is amazingly quick),' the publication stated.

'And if a factory has worker performance issues two days a week, that factory is likely to have issues overall.

'There doesn't seem to be any direct connection between the build quality of the vehicle and which day assembly was completed.'

Earlier this summer, Chevrolet announced it is axing one of its most iconic cars as the automaker moves towards electric vehicles.

The last Chevrolet Malibu, which has starred in movies alongside Ryan Gosling and Denzel Washington, will roll off the assembly line in November.

General Motors has sold more than 10 million Malibus worldwide since 1964.

The gasoline-powered sedan was a stalwart of family garages for decades after launch.

But sales started to decline in the early 2000s as the SUV became popular and pickup truck sales grew.

However, it was President Joe Biden's push for for automakers to move away from gas cars to electric has proved to be the final nail in the coffin for the Malibu.

The Detroit automaker is investing $390 million at its Kansas assembly plant to build next-generation Chevrolet Bolt EVs instead.
