<prompt> Human: Nissan Maxima 2003 4dr, around 151,000 miles on it. I recently took it in for a tune up and the mechanic gave me a quote for the things he said should be repaired. It currently gets me from A to B with no troubles at least known to me and Im wondering if its worth repairing or if I should just ride it out until it quits on me. Im not mechanically inclined, so I dont know which repairs are necessary and which ones I could put up with. I also dont know how long cars like these last for. I would be able to pay for these repairs, but its not ideal as it would cut greatly into my total savings. If someone could advise me andor direct me to the resources to inform myself I would be greatly appreciative. Thank you in advance.

Do you have a good history with this particular mechanic? If not, it may be worth getting a second opinion. A good, fair, trustworthy mechanic is worth hisher weight in gold.Heres what Id do in your situation...Get a second opinion.Tires: How low is the tread? If you put a quarter in the tread gap with George upside-down, can you see the top of his head? If so, the tires need replacing. If not, you still have some time left.AC Compressor: optional. If youre fine with the functioning of your AC currently, then leave it be.Power steering hose: Have you noticed any puddles under your car that may indicate a leak? If not, Id let this one slide too.Brakes: Did the mechanic tell how much is left on the pads? If they are metal-on-metal then they do need replacing. Brakes are important. Rotors and calipers Id hold off on unless the second opinion mechanic says they also need replacing. Tie rodsalignment: Alignments are usually included in getting a new set of tires. Tie rods Id skip unless one is broken.
