Need info on packages

[kmsal]

I'm looking to purchase a 99 528i. I'm told it has the sport & the premium package. I know it has the sport, but can anyone tell me what the premium package is suppose to be? I know that there is a sport-premium package also. What's the difference? Does anyone know where the option codes can be found on the vehicle? I'm new with BMW so any info would be greatly appreciated.
Thanks

sport premium should just mean that it has both the sport and premium packages. However, I know there are overlapping things. For example, the seats should be the sport seats, but it won't have as many adjustments as if it were the one just w/ premium package. I think that's how it works.
