When it comes to dramatically expensive cars, fewer out there do it better than Koenigsegg. And a perfect example of this is the Koenigsegg One:1. It's 2,998 lbs of pure power, pushing 1,341 horsepower. But according to its maker, it's not expensive enough.

They don't mean all for all seven of the models ever made, but for one specific model heading to auction. Bonhams' is getting ready to auction off a Koenigsegg One:1 for an estimated value of $1.8 million to $2.37 million.

Koenigsegg believes this to be a gross understatement, claiming that other examples have sold for twice that, at around $6 million. They're so adamant about the pricing that the brand offered to purchase the vehicle themselves for over the asking price in a pre-auction sale. They were rejected, however.

The automaker appears to be concerned that allowing this sale to go through at such estimates will drastically reduce the value of the vehicle.

One reason as to why the vehicle is estimated lower is because of its history. The particular model used to belong to Teodoro Nguema Obiang Mangue, the son of Equatorial Guinea President Teodoro Obiang Nguema Mbasogo. It was seized by the Swiss authorities in 2016 after he was found guilty of embezzlement of state funds.

Regardless of Koenigsegg's feelings, the vehicle will be going on the auction block on September 29, alongside an Aston Martin One-77, Bugatti Veyron, Ferrari LaFerrari, Lamborghini Veneno Roadster, and McLaren P1. The proceeds of the sale will be donated to social programs in Equatorial Guinea.
