2004 - 4.8 options, service, recall info

[okitalia]

Newbie here contemplating a Imola Red 2004 4.8 with only 34,000 miles. 35k asking price

Can someone please point me to a link on how to determine the options on a 4.8. I seem to find conflicting info. and would like to know before negotiating the purchase. For example, does a heated steering wheel come on an options package?

Also, I was curious about the BMW servicing and if I should get an extended warranty. Need advice on potential service costs.

I founds on Cars.com 4 recalls on this model. Is that accurate.

Thanks so much in advance for any advice. I
