Hello,
I'm the developer of a new Classic Car VIN decoder website named Decode
This! (
http://www.decodethis.com) We are a single source for decoding
classic American VINs as well as providing detailed information on
those VINs.
We're able to decode all Fords between 1960 and 1969 (Including
Mustangs 1965 through 1973), 1960 to 1967 Chevrolets, 1966 through 1971
Chryslers (including Dodge and Plymouth) and a variety of other models.
Our Mustang decoding has the greatest range of descriptive text added,
mainly because I'm a MCA member and a Mustang-lover at heart.

Try
http://www.decodethis.com/9T02Z123456 (where 9T02Z123456 is a '69 Boss
429 VIN) for an example of the VIN decoding we can do.
We also offer the only classic car WAP VIN decoder (decode VINs using
your phone or PDA wirelessly) that I know of. We're constantly adding
new VIN patterns to our database, so if we don't decode your car today,
check back tomorrow... Please contact me if you need more information.
Also visit our blog at
http://blog.decodethis.com for a constant update
of what we're doing!
Thank you,
Richard Brown
