I am planning to go look at a 1969 500L that appears to be in very good condition from the photos. My first concern is the lack of paperwork that is available with the sale regarding any history and obvious restoration work that was done. If it runs and the body looks good regarding rust etc. should I be too concerned about the paperwork? The price seems fair and I have been doing my research. I have the Essential Buyer's Guide, it has a current APK (MOT) and is registered. Thanks!
