These days, it's par for the course that a supercar can hit 180 mph or more. Even some of today's more regular sports cars can go that fast! But, it was a different story 30-40 years ago. Back then, if a car could go that fast it was a proper achievement. One of those cars that managed to do this is a Lamborghini that has passed into legend since. That's thanks to it being the ultimate variant of one of the most legendary cars to ever come out of Sant'Agata. Today's Collectors Are Going Crazy For All-Analog Supercars Via: Mecum AuctionsToday's supercars are incredibly advanced engineering marvels. But they don't have the rawer old-school feel that pure driving enthusiasts love. Because of that, collectors who want that purist feel are going crazy for the older all-analog models. These cars offer screaming engines and nothing that gets in the way of you feeling the road. This includes them having no driver aids, nothing that isn't essential for maximum performance and proper old-school manual transmissions. Lamborghini Made Some Of The Craziest Of Those Old-School Supercars LamborghiniOut of all those old-school automakers who made crazy supercars, Lamborghini made some of the craziest of them all. The Miura has been argued by many to be the first supercar, and things only snowballed from there. Sant'Agata became known for making the maddest cars you could buy, and the car we're about to talk about is no exception. If anything, it's probably the greatest example of how crazy Lamborghini could get. Birthed near the end of the '80s, it's an incredibly speedy wedge that's as raw as they come. The Lamborghini Countach 25th Anniversary Is A Wedge-Shaped Legend That Can Hit 180 MPH RM Sotheby'sThe Lamborghini Countach is often thought of as the prime depiction of the supercar excess of the '80s. No variant of the Countach embodies that more than the rare 25th Anniversary version. It was introduced in 1988, the year the Lamborghini company celebrated its 25th anniversary. This version of the Countach has the boldest styling out of all of them. This was thanks to a restyle done by none other than Horacio Pagani—Pagani was an employee at Lamborghini before he started his own automaker. It's also the fastest version of the Countach. Lamborghini claimed that it could reach a top speed of 185 mph, although in practice it was a bit slower than that. Still, it was a Lamborghini that could legitimately hit over 180 mph.The 180+ mph top speed of the 25th Anniversary is impressive enough on its own. What's even more incredible is that it managed this without any modern driver aids at all. You don't get traction control, ABS, or even power steering in the Countach 25th Anniversary, and all of that 400+ horsepower goes straight to the rear wheels through an old-school manual transmission that's difficult to shift. The result of all that is a car that only seriously great drivers can tame. But, like all analog supercars, if you are skilled enough to take it to that limit, it rewards you in spades. It's Very Similar To The Countach LP5000 Quattrovalvole Bring A TrailerWhile the 25th Anniversary was its own variant, it actually wasn't that unique. If anything, it was a heavy re-work of the LP5000 Quattrovalvole that came before it. The 25th Anniversary used exactly the same powertrain as the LP5000 Quattrovalvole. This included a four valves per cylinder (hence the name) 5.2-liter V12 that produced 420 horsepower in fuel-injected versions and 449 horsepower in carbureted versions. The fuel-injected version of the engine was used in markets with tougher emissions regulations, such as the USA. It Was The Final Classic Countach Variant Made The 25th Anniversary wasn't just the ultimate evolution of the Lamborghini Countach. It was also the curtain call of the classic version of that model. The 25th Anniversary was produced until 1990, the point where its replacement (the Lamborghini Diablo) was ready to go to market. While the Diablo was a fantastic car and an improvement over the Countach in many ways, people still preferred the more aggressive wedge and rougher character of the older car. That makes the 25th Anniversary a truly special Lamborghini. It's the ultimate evolution of a raw car that symbolized the excess of the '80s, rather than a more rounded and more refined car for the decades that were to come. It's One Of The Most Valuable Lamborghinis On The Used Market LamborghiniThanks to its rarity value and that it's the final (and ultimate) Countach, the 25th Anniversary has become one of the most valuable Lamborghinis around. It's worth an average of $643,844 these days. That value is only going to go up, too. A very low-mileage 1989 example recently sold for $717,717. If prices keep going as they are, it might not be long before a 25th Anniversary Countach sells for a million dollars at auction! The LP5000 Quattrovalvole Is Also Incredibly Valuable Bring A TrailerThe 25th Anniversary isn't the only '80s Countach that's become incredibly valuable. The LP5000 Quattrovalvole it was developed from is also a must-have for collectors, and that's bumped its value up massively as a result. The LP5000 Quattrovalvole has an average used value of $717,821 right now, and a 1987 example sold for $980,000 very recently. Like the 25th Anniversary variant, it's likely not going to be very long until the LP5000 Quattrovalvole is a true million-dollar car.Sources: Bring A Trailer, Classic.com, Lamborghini
