Another online-only car auction is going up on the block.

For its European Sale auction, auction house RM Sotheby’s decided to shift to an online-only affair, similar to its ongoing Driving into Summer online-only auction. In particular, it will feature the Petitjean Collection, offered entirely without reserve.

The Petitjean Collection is an incredible single-owner collection that took half a century to amass, according to RM Sotheby’s. Marcel Petitjean, its current owner, is a French ex-race car driver that put his money toward a collection of rare and valuable cars starting in the late 1960s with the intention of starting a museum.

He seemed to have a particular affinity for Lamborghinis as there are nine in the collection.

The auction house says that though the cars have been kept in a dry storage facility, they haven't been driven in years and will need recommissioning if a buyer wants to drive them.

The Petitjean Collection will go up for auction between June 3 to June 11. There are nearly 100 cars in the collection, including two Porsche tractors and nine Lamborghinis: two Countach models, a Diablo, an Espada, an Islero, a Jalpa, a Jarama, a Miura, and an Urraco.

There are almost 100 cars in the Petitjean Collection, which will be for sale without reserve as part of RM Sotheby's online-only European Sale auction on June 3 to June 11. Nine of them are very special Lamborghinis.

---

This is a 1971 Lamborghini Espada.

---

The Espadas are easily identifiable through their extensive use of rear glass.

---

Here's another look at it. It looks like a greenhouse.

---

The interior has some gorgeous wood trim.

---

And it could seat four!

---

This is a 1971 Lamborghini Jarama 400 GT.

---

It's one of the rarest Lamborghinis ever made.

---

A mere 177 400 GT models were ever produced.

---

Unfortunately, there's some engine damage on this one that needs repairing.

---

It was added to the collection in 2010.

---

Ah, the 1968 Lamborghini Miura.

---

It is widely considered to be one of the most beautiful cars ever made.

---

It has a mid-mounted, 4.0-liter V12 engine.

---

The Miura is also recognized as the world’s first supercar.

---

It was also apparently the fastest production car of its time.

---

This one is estimated to sell for at least $760,000.

---

The 1986 Lamborghini Jalpa, on the other hand, looks far less radical than the Miura.

---

It still maintains those beautiful mid-engine proportions, though.

---

It was supposed to be an entry-level sports car.

---

Basically, the Gallardo of its day.

---

That blocky instrument cluster is cool

---

This one is a 1974 Lamborghini Urraco P250.

---

Lamborghini only ever made 520 Urracos.

---

It was intended as a competitor for the Ferrari Dino and Alfa Romeo Montreal.

---

All the gauges lined up in a row like that is a good look.

---

This particular one has a replacement engine.

---

The 1970 Lamborghini Islero is perhaps the least-known Lamborghini.

---

Lamborghini only built 226 Isleros.

---

Their styling shows restraint and class. Ferruccio Lamborghini himself drove one.

Ferruccio Lamborghini's personal Islero wasn't just any old Islero, however. It used a Miura-spec V12 engine and wore a gorgeous coat of powder-blue paint.

---

This isn’t the only Lamborghini Countach in the Petitjean Collection.

---

But it is a 1979 Lamborghini Countach LP400 S.

---

It has just 13,800 km on the clock, which is approximately 8,600 miles.

---

It's finished in a lovely dark blue paint.

---

The inside is also blue but with white seat insets.

---

This is the other Countach in the collection — a 1984 Lamborghini Countach LP500 S.

---

Unlike the rounded lines of the Miura, the Countach's looks are made of sharp angles and straight lines.

---

The engine produces 375 horsepower.

---

It's a 4.8-liter V12. Naturally aspirated, of course.

---

The car has a claimed top speed of 160 mph.

---

This red one has fewer than 9,000 miles on the clock.

---

RM Sotheby's expects it to sell for at least $272,000.

---

The interior is perfect.

---

Then there’s this 1991 Lamborghini Diablo.

---

The Diablo replaced the long-running Countach.

---

It represents Lamborghini’s foray into the ‘90s and thus more modern times.

---

This was a car that definitely adorned many bedroom posters.

---

The interior is pretty refined despite what the car looks like on the outside.
