For anyone buying a Porsche of the modern/recent era, the overrev data is extremely significant. Porsche won’t warranty, and top independents won’t sell, cars showing ignitions in the top range of overrevs,as recorded by the car’s ECU. Cars which show significant overrevs, particularly in the recent past, are very hard or impossible to sell, or sell at a significant discount. This is particularly so for manual cars which can be accidentally shifted down from, say, 5th to 2nd at high speeds. So my question is: this is a Big Deal for any buyer of a used 911. Or a seller - try and sell a 997 GT3 RS 4.0 with too many ignitions in the wrong range, and you won’t. But in all the years I have been on this forum, I have never seen the subject mentioned in the context of Ferraris. It seems Ferraris don’t measure overrevs (or don’t do so in the same way). But if the issue is a potentially terminal deal breaker for Porsche buyers, how come it doesn’t even figure in the consciousness of Ferrari buyers? I know a lot of people here have both. a glib response would be that Ferrari engines are made to be revved, but I think no more so than a RS Porsche engine. So, either overrevs don’t actually matter, or Ferrari buyers are purchasing potentially terminal problems on a constant basis. any expert views like to weigh in?
