I really need some opinions. I had my 2011 MDX in for inspection this morning. My MDX has just passed 100k miles recently. I love it and would like to keep it as long as possible. Everything passed smoothly but the service tech. recommended several big ticket maintenance items: $1,295 for a timing belt replacement (just as a precaution), $325 for spark plugs, $275 to replace a seal on the transmission that has a very slight leak $139 for brake system fluid exchange for a total of just over $2,000 in work. Any opinions on how important it is to do these things now? I'm torn between wanting to be proactive but not wanting to be upsold too dramatically. Thanks!!
