Ok I know this has probably been answered a million times before but here we go again how hard is it to replace the compressor, the front air struts, the rear air springs and solenoids, so basically everything. I am asking because my wife wants to know about Christmas presents so I was either thinking of a spring conversion kit or rebuilding the air suspension. What do you guys recommend?I like the air suspension but I like the fact of not worrying about finding my car slammed because something failed. I have read about the conversion kit and it does not seem hard at all. Thanks
