330 engine has quite a bit more hp than 325, feels like a lot more.
11K miles is less than 20K+
It has the options you want
I use the seat heater all the time in the morning here in cold and rainy Nor Cal. You may need to get a "compatible cell phone" to fully utilize BT, but it's another feature I really like too. Logic 7 in my AMG sux. Don't have it in the BMW, so I'm neutral there.
Do it.
What's the inservice date? earlier or later than yours?
