This is not a debate thread, I just want to see which 5 of the many cars in GTA Online are your favorite, and why you like them so much.
Here are mine, in no particular order:
I've always loved the GM A-Body cars, like the Cutlass and the Chevelle. Since the Sabre is a mix of the Cutlass, Chevelle and Buick GS, naturally I'm drawn to it. Here is mine. I tried to keep it minimalist. It's not all that fast and doesn't handle well, but can be a lot of fun in certain circumstances... and it ALWAYS looks good.
The 57 Chevy is hands down one of the most beautiful cars ever made. Although I'm not entirely fond of the headlight design on the Tornado, the rear and sides are gorgeous. It handles surprisingly well and carries a decent amount of speed, so you can cruise the streets of LS, but still make a hasty escape when needed.
If you're not sensing a theme here, I'll spell it out for you: I love classic American cars. I love classic cars in general, but American cars in particular. Sharp design with a beastly V8 engine under the hood. Not sophisticated, but it doesn't matter, that's entirely beside the point. The only things that irk me about the Coquette Classic are the headlights, and the engine note. If it had sounded more like the Pheonix, an untamed, raw V8 sound, it would be more satisfying... but as it is, it's very fast and once you figure out the handling, it's a drifter's dream.
Despite a few decades of mostly abysmal offerings in the automotive realm, General Motors has shown they are finally pulling themselves together. No car is proof of this more than the '14 Corvette Sting Ray. Incredible looking, well built, lightning fast with superb handling - truly an American sports car that deserves respect. Seeing it translated into GTA 5 made me happy, and I'd even go so far as to say I prefer the GTA's Coquette design over the real thing. One of, if not THE best looking car in the game, and it's hard to deny the engine sound is almost certainly the best of any other car in the game.
Although I respect the technology, I think super cars are just incredibly impractical and therefore I just don't get excited over them. I don't see the point in owning a car whose full potential you'll never be able to experience, unless you actually take it to a race track. Cars like the Corvette that can make a practical every day driver are far more appealing to me... but, since GTA Online is a hostile place and those with super cars tend to have the upper hand, I settled on the Entity XF... and I love it. All wheel drive, surprising off-road capability, ridiculously fast, excellent handling and a near bullet proof rear end makes this my go-to car when things get hairy. As with my Coquette, it's painted all black to blend into the darkness.
