In my garage I will get a 1960 Impala and the Kawasaki Ninja (Also known as Voodoo and PCJ-600 respectively) Those will be my cruisers, but I also want to have a Countach for a while and keep a Harley Davidson handy.
Oh, and the CRX will be fun because I own a similar car.....But I will want to own every car at one time or another and keep it in really nice condition.
Sometimes, to elongate gameplay, I drive around and follow traffic rules, and stop for lights.
In GTA3 when I was driving around following the law and someone bumped me, I would get out of my car and car-jack them so they would be out, and then I would get back out of their car and kill them as they lay on the street.
Now in GTA: Vice when someone bumps me, I can get out and bust off a few rounds of my 9mm thru their window and spray their brains all over the window, and get back into my car without as much hassle.
