Classic Car insurance is a funny thing, not unlike our prized or passed down firearms, that are NOT replaceable. I am not sure who does classic car appraisals in the Metro Denver area and honestly I don't think it matters. If you do get appraisals both should be detailed to the point of ad nauseum. Insure both treasures not only for what you paid but the replaceable value, both monetarily and emotionally speaking. This may require additional insurance and rider on your current homeowners insurance (be careful, claims can be red flags when you go to sell your home) or additional insurance via your car policy...or a seperate policy all together. Keep in mind that insurance companies will fight you every step of the way if you need to file a claim after a "total loss" and appraisals may not be enough. Receipts and other documentation will be required to get what your firearms and your sweets a$$ EB are truly worth.
That's my take but I have been wrong before.
