Hi everyone. I'm looking at at 2004 Z4 and thought I would run a few issues by everyone for advice. The car looks super nice in the pictures I've seen. It's a purple color with deep shin e to it. It currently has a few issues and may have others. I definitely want to drive it before I buy it get a feel foe suspension or drivetrain issues if there are any. I've watched some videos on you tube and kind of know what to look for. I understand parts can be quite expensive if needed. I'm thinking valve cover gaskets, coolant tank and suspension bushings. Are there aftermarket sources for replacements? Also struts, ball joints and tie rod ends if needed.? Thanks for any input you may have.
