There are two considerations; style and functionality. Often cars came with huge linear speedometers, no tachometer, and “idiot lights” to monitor key functions and sometimes faux wood grain or fabric inserts. Not only can you update the look of the dash by selecting a matte black, brushed aluminum or carbon fiber finished panel (and trim pieces, with some applications), and equip it with gauges styles that range from classic to contemporary, but it’s easy to keep tabs on the systems and spot things like declining oil pressure and voltage or increased water temperature. This warning lets you take corrective measures before it’s too late.
