I would suggest to see the maintenance service record on the zed. So u have a good idea of what common, small zed problems has been dealth with or have not been dealt with. Especially with pre-face lift zeds, there are small problems with the convertible top, rear coil springs, random squeaking, window regulator, rain sensor air bubbles to name a few. Browse around the problems forum and you'll see a common trend in all the problems with the zed. Otherwise, transmission and engine are top notch. I would keep an eye on the Miles per gallon and the Average MPH to have an small hint to how the car was driven.
