I am buying a 1998 ML320 from a friend. Has 72K miles. Basically sound condition, but needs some TLC. I was wondering if anyone could give me a rough guesstimate about how much to do a complete tuneup, fluids, plugs, etc? Will have to replace the fuse blower motor ( at least we think that is the whining sound cause), is this a DIY job? Also need to replace the passenger side mirror housing (his garage was a little narrow! ) and would like to know if this could be DIY and if so where to get the part and instructions? I am preparing to get right with more DIY stuff to keep this ride on the road because I live over 4 hours from the nearest MB dealer and based on what I read most places, they don't do good service and are too expensive. Also need to put new rubber down, thinking Michelin Cross T's, anybody have better ideas? Thanks for the input and responses.
