Hi all, I have a 2006 facelifted E66 10 years COE expiring this Oct 2016. The engine is still very smooth and car very quiet on road. I am considering to renew 10 year COE. I understand the potential maintenance & parts replacement costs. Do you think its feasible and worthwhile to keep this car? Any E66 owners who have extended/thinking also of extending COE? Tks and appreciate your advice.
