the injectors arent necessarily a major worry. The internal springs within the injectors that prevent fuel from dripping into the cylinders when the car is off, can wear out over the years and can contribute to long/hard starts after the car has stopped for awhile. That was my personal experience with mine. And a set of 8 Bosch are not overly expensive at all, and are a fairly easy job to replace. (dont strip the allens on the retaining bracket that holds them in). But the fact that he simply doesnt replace them (combined with him not taking the time to fix the sunroof, combined with what is listed as 6 total owners?) sends a certain message not befitting of a car priced at the upper end of the range..
