<prompt> Human: Hello PF,How do you decide when its time to sell a vehicle instead of doing the maintenance? My pickup truck is almost 8 years old, approaching 100,000 miles. I rotate tires and change the oil every 5000 miles and replace the standard wear items whenever they need to be replaced. Recently Ive had a lot of new vibrations, noises and various other items start falling apart. Based on estimates I just got, I have 2-4k in repairs to fix all the issues, but my gut says this is the beginning of a long road chasing difficult to find vibrations that are ripping my truck apart. KBB values the truck around 15k. When do you decided to retire a vehicle instead of slowly rebuilding it piece by piece?  <response>: Mechanic here. I tell my customers like this if you spend less per month on repairs than you would on a payment then keep your current vehicle. 100,000 miles really isnt a lot on modern vehicles.
