2001 Saturn SL2 . Stock mechanicals, upgraded brakes and tires, sway bars. Some weight deletion. I just about redline it every shift, corner confidently and generally toss the car around with as much vigor as the safety of a given situation allows. (Before some asstard misinterprets that, I don't drive like a douche in traffic.. you wouldn't even notice me in traffic unless I'm at the front of a stoplight and you notice I'm the only person who actually goes when the light turns green) .

No part of the car has exhibited any sort of failure or excess wear. I have only had this car about half a year.

2002 WJ Overland - reworked suspension, 32" tires, transmission internals updated + valve body kit, updated brake calipers + performance pads, matched heads/exhaust/intake port work. - this vehicle gets used as a utility, all seasons off-pavement touring, towing, hauling, lots of interstate out West where the states are big. Vehicle has had a number of minor failures but apart from eating motor mounts on a regular basis they have not seemed related to use. Things like the HVAC blend doors failing, heated seats failing, a rear power window mechanism failing, interior trim pieces (in front, not where cargo goes in back) falling off... etc. . Have had this vehicle several years.

Overall my experience has been that vehicles tend to be able to tolerate a lot of heavy use without complaint; what they don't tolerate is neglect. So I don't neglect my cars, simple as that - they always have fresh fluids in every part that takes fluid and they always get fixed when something breaks, ASAP. So I have two cars, both over a dozen years old and on which everything works genuinely like new except the driver's side heated seat on my Jeep (I live in Arizona, it hasn't been a priority) and the windshield washer in the same vehicle (tank is geometrically incompatible with larger tires.. I am currently in pursuit of a good unit for relocation)
