While buying a Bugatti has never been cheap, models such as the EB110 and the Veyron are increasing in popularity among collectors, which means that their prices have gone up as well.

According to a report carried out by Classic Analytics, the average value of the Bugatti EB110 GT has jumped from 280,000 euros ($314,000) in 2011 to a multiple of that amount. In fact, in February of this year, a 1994 EB110 Super Sport was auctioned off for 2.03 million euros ($2.33 million).

“When Bugatti launched the Veyron in 2005 it moved more into the focus of interested buyers, and this had an impact on the price development of many models. Since the appearance of the new Chiron in 2016 there has been a significant price boost among more recent historic vehicles such as the EB110,” said Classic Analytics exec Frank Wilke.

Since Bugatti only produced 128 units of the EB110, aiming for a less exclusive Veyron 16.4 model might be the way to go if your budget doesn’t extend beyond $2 million. The French automaker produced 450 Veyron units, selling them at prices of at least 1.16 million euros ($1.3 million). Right now, it’s nearly impossible to find one for less than 1.3 million euros ($1.46 million), especially if you’re looking for any of the special versions.

“Demand for the Bugatti Veyron has increased in recent years and with it the price – especially prior to the launch of the new Chiron. In fact the price level of some Veyron vehicles is the same as that of the new car,” added Wilke.

As for the Chiron, it’s definitely too early to talk about future value since Bugatti has yet to deliver the remaining 100 units to its customers.

Meanwhile, the world’s most expensive car is thought to be a Bugatti – specifically the Type 57 SC Atlantic. Only four units were ever produced between 1936 and 1938 (three of them still in existence), and while they are not for sale, they could fetch prices of around 100 million euros ($112 million).
