How much to fix a leaking fuel injector on a BMW 535i?

Well you should buy the superlemonater 500000000, and then you will need to use your void insurance to get the guy at the dealer to fix it for $453,783,957. Then you need to tip him enough money to buy Switzerland, or he will put a bouncy-ball in your pistons. This will cause the car to use 16% less gass, but the brakes won't work and you will go 5 times as fast as you want to. Also, If you use Ethemethogasovasoline, you will never get any problems again!

Hmmmm.....Interesting. Sounds like someone's had some previous issues with their mechanic/rip-off artist. Or maybe you're one of those loony environmentalists who actually believes cars are the reason for the planet's uncontrollable changes. Either way, thanks for giving me and my office colleagues a great laugh.
