Classics are rare beauties that should be treasured. They tell stories about a particular point in history. Modifying these classic cars should be a crime. We're all for modification don't get us wrong, modifying a car enhances it in some way that isn't part of the auto manufacturer's specs. And that's a good thing when you know what you're doing.

Most times, owners make modifications to their cars to improve their aesthetics or performance. But these classic cars rank among the best, getting your hands on one would cause some hassle. If you're lucky to lay your hands on one of these, for the right amount of cash, modifying it should be sacrilegious. Maybe even a criminal offense.

The Chevy Corvette was named after a small maneuverable warship. The Corvette, commonly referred to as the 'Vette', is America's most collected vehicle. And for good reason.

The second-generation Corvette which spanned from 1963 to '67 ranks among the most iconic American cars ever made. Decades later and this front-engine classic is still fresh and appealing. Stylishly nicknamed Sting Ray, getting your hands on one now is decently possible for three times the price back in the day. Those who appreciate vintage classic would have no problem with that and modifying it would not factor in their thoughts. But if it ever does, resist the urge.

9 DeTomaso Pantera

Via: mecum

The Pantera is another Italian car on the list but by a different manufacturer, DeTomaso. This Italian beauty has a Ford V8 engine, a seamless blending of American engine, and Italian style. Absolute class. The Pantera was the highest-selling model of DeTomaso producing more than 7,000 units in its twenty-year run. But make no mistake, the Pantera is no slouch to collectors, and for good reason. This American-powered classic tops at 159 miles per hour. Back then, it provided an alternative to Ferraris of that era. Should you lay your hands on one, don't make the mistake of a modification.

8 Lamborghini Miura

Via: HiConsumption

When it debuted in 1966, many considered the Miura to be the sexiest car ever built. Whilst it may no longer hold that spot today, it's still considered stylish. It was a mid-engine Italian speedster designed as an alternative to the Ferrari. And it lived up to the hype.

This classic was a pivotal point for Lamborghini and it still has cred. With variations of the Lamborghini like the Aventador and Veneno making waves on the tracks, it's easy to disregard the Miura. But it's an all-time classic.

7 Porsche 911

A successor to the famous Porsche 356 of 1963, the 911 was even more popular. An amazingly well-built sports car designed for the tracks. The vintage classic is a high performing auto that lived up to every hype. A car built for automotive competition, Ferdinand's classic ranks among the most successful competition cars. Even by present-day standards, it would hold its own on the track. As far as cred goes, this beauty has plenty. Like any vintage car worth its salt, getting your hands on one won't come cheap; and when you do, you'll know the Porsche 911 needs no modification.

6 Rolls-Royce Dawn Drophead

Via: Robb Report

The Rolls Royce is a distinct auto brand. Having a Rolls Royce in a parking lot is sure to garner attention. And in typical Rolls-Royce fashion, the Silver Dawn Drophead makes a statement.

Built to mark the dawn of a new era, the Silver Dawn solidified Rolls-Royce's superior craftsmanship, while bringing the company into a modern age after the war. In usual Royce fashion, not many were made during its run from 1949-1955. As such, this vintage beauty is hard to come by even with cash in hand. Those fortunate to have one in their garage, wouldn't modify it after the hassle.

The Ferrari 308 GTS produced from 1975 to 1985 was a two-seater V8 mid-engine that represented elegance and style. With a top speed of 152 miles per hour, this steel-bodied beauty launched at the 1982 Paris Motor Show. It raved back then, decades later it still raves today. And the television series Magnum, P.I. certainly helped. It's an all-time classic fans love, modifying it should be a criminal offense.

4 Shelby Cobra

Via: Motor Authority

The Shelby Cobra came into being when retired American race car driver Caroll Shelby wanted a modified car that could accept a V8 engine, which is ironic per the list. Caroll Shelby was also an automotive designer, and his brainchild the Shelby Cobra is an all-time classic. This high-performance beauty was built for race but never made it to the tracks due to mandatory requirements. As such, it was discontinued, making the number of cars available very limited. Nicknamed the 'original Shelby', anyone fortunate enough to have one parked in the garage should know not to modify a classic.

Falcon wing doors! This is elegance redefined. If falcon wing doors are cool today, imagine back in 1954. Ok, it's called gullwing, the falcon wing is for Tesla's Model X. When the Mercedes SL 300 debuted after the war, it was the fastest production car at the time. In fact, no one expected such a car from Mercedes. As the first direct-fuel injection series production car, it could do 160 miles per hour. Certainly a vintage classic, not many are available even with your cash. Most owners still own their original from back in the day, and with a car as the SL 300 Gullwing, it's easy to see why. Think the owners would ever want to modify theirs?

2 Jaguar E-Type

This classic is a sports car mainstay. Based on the D-Type, the Jaguar E-Type is a staple of British motoring history released in 1961 by Jaguar Cars. It was a combination of beauty, performance, and class, and was once referred to as "the most beautiful car ever made" by Enzo Ferrari himself. This classic icon could do 150 mph, and with better brakes than most cars from the same era. Not many can lay their hands on one today, and the few who can, wouldn't dare modify this beauty. And if they dare, well, it should be a criminal offense.
