Car manufacturers are investing more and more effort into aesthetics. Most modern vehicles have amazing designs. They're packed with technology, signaling status with expensive and exotic materials. But sometimes we bump into ridiculous details that ruin the whole design.

For many car owners, the interior isn't the most important part of the car, and it doesn't influence their buying decision. But people shopping for sports cars and supercars pay much more attention to little details, including interior design.

The truth ism the cabin styling matters almost as much as the exterior design. As long as you're on the road, you will spend all the time inside the car. While most new sports cars and supercars have awesome cabin style, some manufacturers need lessons on style.

You will be frustrated to no end if you spend some time in these cars. Here are 15 sports cars and supercars with unsatisfactory interiors.

The interior of the 5th-generation Camaro visually represents the 1969 Camaro but has the poor quality and cheap materials of a 1993 Camaro. The interior looks and feels spartan with its uncomfortable seats and edgy plastic details. Most importantly, it is downright unsafe with tiny windows. These were supposed to look manly, but something went wrong.

TVR cars usually have very minimalistic interiors, but the Sagaris has taken it too far. Molded leather surfaces create ridiculous shapes. You get a boring steering wheel, an uncomfortable gear shifter and peculiarities like a button to open the door near the stereo. Even worse, the color doesn't suit the main concept.

13 Jaguar XFR-S

When it comes to the interior design, the Jaguar XFR-S is vintage in a bad way. The slabby dashboard is made of aluminum trim bits with cocktail blue lighting, which betrays the cabin's age. Then there is a small 7-inch touchscreen with a low resolution. The graphics look cheap and outdated.

12 Ford Focus ST

Owners of the Ford Focus ST faced some serious coat peeling problems. There has been reported peeling on the steering wheel but the company said it's "normal wear and tear". Aside from that, Focus rivals have surpassed the interior design in terms of luxury and tech. It certainly doesn't have the wow factor.

With first-rate cabin materials, the 2012 Lexus LFA interior design was supposed to be user-friendly and modern. However, the number of buttons and switches inside the car requires some study.

The 1985 Subaru XT's dramatic interior styling defines the car, for good and bad. The cabin is wild. For some reason, designers felt compelled to add blocky pods at the 3 and 9 positions on the steering wheel, and then fill them with buttons. Add many shifters, and you have a recipe for confusion.

6 Aston Martin Lagonda Series 2

The 1976 Aston Martin Lagonda Series 2 was the car ahead of time in terms of technology and performance. However, its interior design was poorly executed. It was the first car with a digital dashboard and something went wrong. It was also the first car with a computer-control system, which was very slow and irresponsive.

5 Delorean DMC-12

Is the Delorean DMC-12 a sports car? if it means that the interior design doesn't have many comfort features and offers very little legroom, then yes. But if it means that the car is fast and powerful, then no, the DMC-12 isn't a sports car. It tries to be a bit of everything and fails.

4 Panther 6

With the Panther 6, the company promised performance and comfort features that have never been seen before. However, these claims are unsubstantiated as no car was ever seriously test-driven. Its electronic instruments are confusing, and electric seats and windows don't work as they should. There is a built-in TV that looks redundant.

3 Dodge Avenger

Comfy seats and a good handbrake can't compensate for the monstrosity that is the remainder of the Dodge Avenger's interior. There are cheap, hard surfaces all around the driver. There are no patches of upholstery on the doors. Everything is molded from cheap materials, lending the impression that the company was on a shoestring budget.

2 Pontiac Grand Prix

The 5th generation Pontiac Grand Prix is known for its terrible dashboard. All you see are buttons and more buttons. If you like dozens of useless controls around you, you will enjoy the interior design. It got 4 light buttons, 4 more for the wipers, and a dozen on the steering wheel.

1 Honda Civic

When we look inside the Honda Civic, words like "hollow" come to mind. We can't expect exotic materials on a C-segment car, but the company could at least try. If you know how those fiber things that grille restaurants use to serve taco shells in feel, you understand the poor quality of the Civic's interior.
