2004, E46 330i Manual Advice needed

Howzit guys,

Really need some advice, I am considering buying a 2004, E46 330i Manual. Car is still in awesome condition has 203 000kms on the clock and still in a very good overall condition.

I would like to know what I should look out for common issues, maintenance, and one big question is what is the consumption like. What can I expect more or less fuel wise.

Thanks For looking
Fuad
