Car - Infernus
Reason - It is the only car which is mixed in speed and controllability. This car is great for drifting, performing barrell rolls, jumping over buildings.
Motorbike - FCR-900
Reason - It has just a tiny bit less speed than the NRG-500 but the only difference is that the FCR-900 knows how to make noise. Great for screech starts before a race.
Plane - AT-400
Reason - Not only being the largest plane in the game, it can also reach the highest heights, go as fast as a hydra jet fighter, and if used properly, can be used to perform stunts.
Helicopter - Cargobob.
Reason - This helicopter is one of the most unique looking helicopters in the game, it is also 1 of the 2 of the hardest to obtain helicopters in the game, unless you have finished flight school with flying colours or have the ability to enter it inside an airport.
Fun Vehicle - Hovercraft
Reason - As Hovercrafts explode in a big group, they smash into other hovercrafts, making possibly some of the biggest bombs in GTA SA
For GTA 3, my favorite is the Patriot.
For Vice City, my favorite road vehicle is the Hotring Racer. My favorite helicopter is the Sea Sparrow.
For San Andreas, my favorite road vehicle is the Feltzer. My favorite helicopter is the Hunter.
I don't have GTA IV, which sucks. But I'm gonna get a PS3 soon, and buy GTA IV.

I have to say I like most of the sports cars - the Cheetah, Banshee and Stinger especially, from both GTA III and Vice City
My favourite Vice City vehicles are probably the Hot Ring Racer (fastest car in the game), the P900 (the ridiculously fast bike) and the Ice Cream Van (for the novelty of it, and selling 'ice cream'!)
In all the games I've never been big on using helicopters, and the Tank is always a great vehicle to use
On San Andreas I enjoyed using the BMX a lot, and other than that, can't really remember
GTA IV I couldn't pick a favourite, maybe when I play it more I'll find one
GTA2 = Anything you could modify with oil slick. That was the best part of that game, watching cars spear off the road.
GTA3 = The Banshee. Always used to go to the car place and get the one behind the glass.
Vice City = My memory gets a bit muddy here. Probably the old Ferrari lookylike.
San Andreas = There was one car I used to do a lot of freeway driving with but I can't remember the name or what it looks like.
I've not played enough GTA4 to find my favourite there.
I miss the way Bubba used to drive 'em :(
GTA III: Diablo
GTA Vice City: Sanchez
GTA SA: Turismo
GTA IV: Turismo
