So I broke down and bought a 2001 x5 4.4i with only 75,000 original miles on it. The x5 is like new inside and out. Besides an engine oil and filter change, what other items would you service/ change? I am debating doing a trans filter drop and fill. SO what would you do?

I also plan on doing some undercoat protection, waxing and interior protection in the coming weeks to preserve the rustfree body and nice interior. Suggestions?

Thanks,
T
