Purchasing used Z, unsure to pull trigger

But if that's in the back of your mind, the risk may not be worth it to you. Not sure how you've been burned before, but a good inspection and test drive should tell you everything you need to know.

The only tell was that the car would overheat after an hour of driving in the summer and overfill the reservoir. It was impossible to tell after a half-hour test drive. I also took it to two different dealers to diagnose this problem and they told me there was no issue (after leakdown, pressure, and chemical tests). After doing a bunch of digging and autopsy did I figure out the whole story
