so long as the car checks out in a PPI done by a reputable outfit you should be fine with the later N63TU engines. I would say i always use the highest octane fuel here in Australia that's BP or Shell 98 RON. Never use fuel with ethanol or lower grades if you can help it. I've spoken to many mechanical people who suggest poor quality fuels, high ethanol content fuels and low oct are just not good for these engines, they really don't like it.
good luck hope you find the 6 series you like, they are fabulous looking and preforming cars!
Thanks everyone. Actually I have to change my profile. I'm in Charleston, SC now. I'm going up to look at the car Saturday. 5 hrs each way, ugh. If I like it I'll have an inspection done by the BMW dealership. They asked if I want a compression test. It's like $400, so it's not cheap, but may seem worth the price. Thoughts? Also, any thoughts on this interior, some times I love it and others it's too much. I guess I'll know for sure Saturday! Exterior is silver.
