Corvette Enthusiasts can use this FREE app look up Years, Models, Options, and RPO Codes to determine the Build, Rarity, Collectability and Present Value of Corvettes from 1953-Present by selecting the condition, the mileage and checking off options. This is a must-have for anyone buying, selling, restoring, or researching a Corvette. More than a book or a website – it is an active, ever-changing database of Corvette Knowledge. Our experts regularly monitor actual sales data and update our database to keep the estimated values current. Use this App to decode build sheets, determine production quantities, and research original costs while you learn about model specifications. Enjoy reading special commentary provided for each year and noteworthy options. The current value numbers listed within the CorvetteDNA application surrounding specific Corvette Models and Options are provided to empower our viewers with guideline information to evaluate Corvettes. When it comes right down to it, the deciding factor that will determine the final selling amount of any Corvette is essentially what someone is willing to pay for it. No one can truly account for the emotional appeal or the personal significance that Corvettes are sometimes measured by. Because of these unpredictable variables, CorvetteDNA neither certifies nor guarantees these values. Consider these values as reasonable estimates you may use to begin a negotiation or make an assessment of a Corvette you intend to buy, sell, restore, or insure. Data and Application Versions are being updated regularly.

Verdict

The call

The clearest difference is ads: Rolls at none against CorvetteDNA's shown.

CorvetteDNA's advantage is review sentiment (79% vs 67%) and iOS requirement (13.0 vs 17.6). On price, rating, ratings volume and in-app purchases there is nothing between them.
