| We recently gave you an overview of just exactly what a Corvette's serial number or VIN can tell you. The Vehicle Identification Number is home to a variety of details, from production number to the less-obvious assembly plant, body style and in some cases, restraint system. In this newsletter, Mid America Motorworks decodes the details in the early Corvette VINs, covering C1, C2 and C3 generations. |
