One concern with a bottle jack is that the top of it is very small. So you don't have a lot of contact with the car. It's easy for a bottle jack to slip...or bend the lifting point of the car if it's not in the right spot. Spend a couple of bucks and get a jacking puck for the top of it. It will help spread the lifting load and keep the top of the jack from slipping.
If you're super-cheap, go down to Play-It-Again Sports and buy a used hockey puck for $3 and make your own.
