The whistlelindiesel tax evasion story surprised many fans, because it did not come from any stunt. Cody Detwiler, who is the YouTuber behind WhistlinDiesel, is facing felony charges in Tennessee because of a car purchase.
These are allegations, not a conviction. Detwiler has denied any wrongdoing, and the case is still ongoing.
Background: The Ferrari Purchase
This case revolves around a 2020 Ferrari F8 Tributo that Detwiler bought in early 2023. He later destroyed this supercar for content, which includes a video whose title was “I bought a $400,000 Ferrari just to destroy it.” Montana plates were also fitted on this car, which proved important in the case.
What Are the Allegations?
In a grand jury indictment sworn on 5 November 2025, Detwiler is accused of knowingly trying to evade Tennessee sales tax of $500 or more on the Ferrari. He faces two counts of tax evasion, and the name of his company, WhistlinDiesel LLC, is also included in the indictment.
Why Montana Matters
Montana does not collect sales tax on vehicles, whereas Tennessee charges 7%, and in Williamson County there is also a 2.75% local tax on top of this. Detwiler himself estimated that this charge is related to “possibly” $30,000 of sales tax. Registering a vehicle through an out-of-state company is a well-known practice, and some states have started being strict about this. This is general background, not legal advice.
Arrest, Bail and Court Dates
Detwiler was arrested on 12 November 2025 and released on a $20,000 bond. His arraignment was scheduled in Williamson County on 19 November. Arrest and indictment are only the beginning of the legal process, and they do not prove guilt.
His Response
Detwiler has maintained his innocence, and has said that this matter is about registering the Ferrari in Montana, where vehicle sales tax is not necessary. He also claimed that the authorities want to make an example of him. These are his own statements, and the court will decide the outcome.
Is It Really “Tax Evasion”?
Yes, in the sense that the formal charge is tax evasion itself. Many headlines also call it a sales tax dispute, because the allegations are related to tax on a vehicle purchase, not income tax. The meaning of this label is not that the court has found him guilty.
Current Status
According to the most recent reporting that I got, the case was going on in Williamson County’s courts until the middle of 2026, and no public outcome has come out. When verified information is available, we will update this page.
Final Thoughts
The whistlelindiesel tax evasion case is a reminder that legal responsibilities also come with high-value purchases, even for those creators who are famous for destroying expensive cars. Until the court announces its decision, these allegations are only allegations. For more, read our articles on his arrest and net worth.
