In the world of car tuning, tuning means improving the appearance and performance of a car. The reworking can be simple, just some tweaking here and there or taken to the extreme limits, adding all kinds adornments and accents that are not only costly but can give the vehicle a distinct, nay, odd look. 
The tuning industry has reached maturity as proven by the different styles that appear on the road. Some tuning packages are customized for a particular and specific car, while some styles can be applied to different cars. Each different tuning style has its own adherents. Some of the styles in vogue are the following:
1. DUB Style. The focus is on the wheels, large wheels. The vehicle is lowered to little inches above ground.
2. JDM TUNING. JDM stands for Japanese Domestic Market, and denotes Asian cars. Emphasis is in sleek, race-inspired style.
3. GERMAN STYLE. Upgrades on VW, Audi, Porsche, BMW and other German made cars. Refined and elegant style of tuning.
4. IMPORT. Modification of imported brand cars for street racing.
5. CLEAN STYLE. Performance enhancements with restrained body modifications.
6. HOT RODS. Classic car modification for extreme performance that can be traced back to the early days of the automobile.
7. LOW RIDER. Lowering of the vehicle’s suspension, and can be applied to trucks and van as well.
8. RAT RODS. Hot rods at the extreme and distinguished for its unfinished appearance.
9. EXTREME TUNING. The focus is on the exterior look rather than in performance.
10. RACING. Giving the vehicle topnotch appearance, e.g., gull wing doors and scissor doors.

An interesting instance of customized and unique car tuning that is in class of its own is told below.
One car owner decided to get his inspiration from a military vehicle, not just a military vehicle but a battle tank. His car is the 1988 model Caprice, a full size car which was produced by the Chevrolet Division of General Motors in six generations from 1965 until the present. The subject car is the 1988 model of the third generation built through the years 1977 to 1990. All efforts were made to give the vehicle a military appearance – green paint with camouflage spotting, a white star at the front doors like those found in a general’s service car, the word “PATRIOT” stenciled in the engine hood, and an American flag at the rear. A feature borrowed from a real tank is an aluminum turret mounted on the hood complete with a gun, and a glass dome where the driver sits like a real tank driver, his seat having been moved from inside of the car. An outdoor vent was even installed near the front doors like those found in amphibious tanks. To this particular car owner and his ilk’s way of thinking, it is the only way to make their car different.
