She's getting close to 100k, well maintained.
Minor mods like intake, and cat back exhaust system.
What numbers can I be expecting for her to last?

Thanks guys.

umm i think op is asking about how long the car will last, up to what number of mileage. it should last indefinitely provided proper maintenance. Oil changes every 7500; coolant change or flush, transmission fluid change, differential fluid change, every 30K are the MUST have major services. Use OEM fluids that are designed for your vehicle. OEM coolant, OEM engine oil, and tranny fluid, and differential fluid. Using the wrong fluid can mess things up.

As far as drive belts go, change or check every 30K as well, some will do it every 15K. Brake fluid every 3 years or 30K whichever is first, and steering fluid every 30K i suppose. Do this at proper intervals and your car will last forever.

There's no reason that your IPL won't make at least 250K with proper maintenance. As you close in on 100K, the one change in regular schedule is to replace spark plugs before 100K. I'd go with NGKs latest ruthenium coated plug with that change.

How many of those miles did you put on?

97k right now

I'm at 130,000 now and I'm running into a spark knock issue. The sound is like a loud knock coming from the engine out of the blue when the car is warmed up and around 1500rpms it'll come loud as ****! And then go away??? From a cold stop. But if I mash the gas harder it won't do it. The dealer said it was because I was using sunoco 93 they have crappy gas and to use shell or Exxon bp mobile one because we dont have Chevron or Texaco in Philly. I did 5 fill ups of Exxon and though the car runs much better but the sound came back. So when I got my car back from the dealer the I couldn't duplicate the sound again after I switched the gas. Now the sound came back.

it happens to the best of us, no worries
