Of the last 2 gens of Z's before the 350,almost everyone that Ive seen has had its share of engine problems and burnt out turbos.I jus call em like I see em.Now mind you Ive never owned a Z,I certainly did consider it before I got into 240s 8years ago,and from all my research and everyone that ive ever known thats had a Z,its always the same story. Most of these problems stem from individuals doing performance upgrades,ofcourse you wouldnt know anything about that having babied your Z for the last 17 years.
