you cannot change the car interiors
There are Pay N Sprays in GTA IV, but they will only change the colour of a vehicle. There is no equivalent of Transfender, as in GTA San Andreas.
No, there isn't. There might be a mod for it though. You can only get mods online.
You can accelerate by pressing up key in GTA SA.
GTA Online (Grand Theft Auto Online) is an open world MMO where you and your friends can get together and do almost anything imaginable. GTA Online has improved from single player for many reasons. One reason is that it has more cars, helicopters, boats, weapons, and more. GTA Online allows you to do Races, Deathmatches, and Survivals. (Heists are yet to come as promised in the GTA Online trailer) In GTA Online you start with nothing. You have just arrived to Los Santos in an airplane and introduced to Lamar's friends or as he says "family." The point in GTA Online is to have the most money and reputation. The more money and reputation you have the more nice things you can buy yourself. Now that GTA Online is new you do not get paid the money you wish to get. But when heists do come you do not have to be doing like 20 jobs and 10 survival missions to be able to get the nice car you wanted. When you play GTA Online there are 2 main things you want. A House and a car. When getting a house it automatically comes with a garage. Depending on how much money you spent on the house is how man cars your garage can hold. To get a 10 car garage i believe you need a $250,000 house or more. If you buy a car online it will be delivered to your garage and you automatically get insurance and a tracker on your vehicle. A tracker helps you locate where you left your car last, and insurance can get you a new car or motorcycle if it is destroyed. Each garage comes with a mechanic that can deliver your car to you anywhere in Los Santos. Once the car is placed into the garage it is automatically fixed. GTA Online has extremely high prices that have a big difference from single player but it still is fun. Personal Note: If you want the baddest house and the Hottest car without cheating or glitching, I prefer SURVIVAL. Survival gives you $20,000 if completed and only has 10 rounds. 3 rounds include helicopters. The easiest way to complete survival is to do Boneyard. Have 2 people guard the inside of the middle building with a shotgun and have people outside ready to take down the helicopters. You can also wait till a new update comes out that will have HEISTS available. Heists pay a lot of money but because GTA Online is an MMO, Heists aren't going to pay as much as single player. From about $95,000-$250,000 depending on what kind of job it is.
