OK, so yesterday I ordered the 128 vert with convenience, premium and sport pkg, plus nav and Sat radio. So this might sound like quibbling, but what about the heated seats and HK audio? I test drove a 135i with HK and a 128 w/o. Not sure I noticed a difference but there's lots of comments on the web about people who wished they had upgraded to the HK audio. As far as the heated seats, I live in Florida, but the sales manager swears I will miss them during our cooler winter nights. Since my partner is a BMW salesperson, I know the manager is not just feeding me a line, and I do look forward to top-down night drives during the winter here (where we Floridians do feel cold even though it's in the 60's ) I have a 2 week window or so to tweak my order - so should I just go for it and get the HK audio and heated seats? Comments from those with experience are very appreciated.
