Since I bought my first bimmer, i'd like to know everything about it.

I'm reading my way true the page's but, hell, it isn't a small forum!
Because of me being a stupid Dutch kid, and a newby on the forum I didn't know exactly what search terms to use.

So, what ís the difference between for instance the 2.5i and 2.5i S?

Also wanted to know were to start with minor modding the car. But I think i'll make a new topic for that one?

theres a 2.5IS? oh, outside the US

i'm fairly sure that the 3.0IS has the M tranny, and it's better tuned, compared to the 3.0i

Look at this www .autoweek.nl/carbaseresults.php?merk=BMW&merkID=8&serietotaalID=64&serienaamID=1011&serienaam=Z4+roadster&srchpage=1&cache=no url it'll redirect you to autoweek.nl (dutch site) and it'll give some specs however I don't see any differences between the I/IS..

(tried to make it an url but because of my lack in post i couldn't, sorry for the big link)
