The old legacy system gave you more accurate information on the engine size. This is important because different motors me different values and there is not always a clear picture of the motor or the hood sticker. For example a Chevy truck can have a 4.6, 5.3 or a 6.0 V8. A Ford Escape can have a 1.6 or a 2.0 Ecoboost and Ford Trucks have I think a 2.7 and a 3.5 Ecoboost option plus 4.6 2v, 4.6 3v, 5.0 and 5.4 V8's. So listing just V6 turbo or 4cyl turbo doesn't work for Ford and V8 doesn't work for Trucks in general. How to fix this? Force the listing to make the seller pick the applicable motor or vin decode so it shows the size motor in the header description.
