Below are some of the most favorite cars used by DX players:
1. Mitsubishi Lancer Evolution 7
Probably the most used, most preferred car by DX players. The most suitable car for newbies or beginners at the start of the game. It has everything, stability, speed and stylish. It can skid and drift very wells through tight corners, depending how good the player is. On top of that, it is a good training car for those beginners who starting to try DX. Me, myself used this car in the beginning and it was impressive. A good car with 6-gears driven to perfection.
2. Nissan Fairlady Z
Nissan Fairlady Z also have been some of the DX players favorite. It has impressive speed, wide and big body, stability and stylish when modified. From my own experience, I don't quite like it as I think it is quite difficult to drift or skid in corners as its wide body(or could be I'm not used to it). However, when a good player used this car, it is one mean machine with 6 gears speed. This car is also used by one of the manga character, Black Bird, when instead he uses Porsche.
3. Subaru Impreza WRX STi (GDBC)
Subaru Impreza made to the favorite car list as this car is the same as Mitsubishi Evolution 7. It has everything, from speed to stylish and well-known for it's stability during corners. It's like a mirror for the Mitsubishi Evolution 7. With 6 gears speed, it is one hell of a car that may difficult your chance of winning if it is used by a very good players.
4. Toyota MR2 GTS
Seldom used but a very good car indeed, Toyota MR2 is one of the competitive cars as it got speeds, stability and also stylish when visual modified. The advantage of this car is that it's tiny body, it able to slip through traffics easier than other cars. When used by a good player, this car is very threatening at times.
5. Datsun Fairlady Z aka Devil Z
The popular car used by the main character of the anime & manga, known as Devil Z, a classic early version of Fairlady Z family. It is stunningly beautiful and fast, with small body and looks meaner when visual modified. On the contrary, I heard that this car also quite difficult during corners. But when anyone can master this beast, it is unstoppable. With 5-gears speed, it is one big threat even for modern cars.
6. Nissan Skyline GTR-32 (R32)
Nissan Skyline, as from early version until now, has never let car lovers disappointed with their cool stylish an monster-ish performance. Speed and stability are common with Skyline family.

This is the second or third most common car used by DX players. As mention before, this car has everything, monster performance and very stylish and mean-looking when visual modified. I, myself, am a fan of this car, in games and in reality. The best Skyline ever made in its own family. With 6-gears speed, this car is one hell of a monster with its strong body and amazing stability during tight corners. It is no doubt the most threatening car in DX+.

Famous in Initial D manga/anime/games, FC3S does not disappoint its fans in DX+ either.

10. Mazda RX-8 SE3P
Meet the famous among its rotary family, appears in movie and an all-time favorite among car lovers, RX8 by now, is the most used car in DX+. This car is also my own personal favorite. 6 impressive gears speed, fast acceleration, impressive corner/turns tackler, and stylish visual modified made it looks like a race machine from hell. RX8 is known for its stability during sharp corners and turns, and also gain title of the sharpest corners tackler. It is very easy to control during a drift/skid and after the drift, it able to accelerate faster. A good car and a favorite among expert players, this car is impressive enough to win any races.
