The Automobile Reference Collection can give approximate values for most cars and light trucks, including many antique vehicles. Here are the two websites we use most often in answering questions of this nature:
"NADAguides.com is the most comprehensive vehicle information website on the Internet today... One of the most popular features of NADAguides.com is the pricing information we publish for new and used cars, trucks, vans and SUVs, as well as classic, collectible, exotic and special interest vehicles, boats, motorcycles, RVs, personal watercraft, ATVs, snowmobiles and manufactured housing. We publish more information about more types of vehicles than any other data provider on the market."
