How to use the guide section
Start with identification
If you do not know the exact item, use a guide before you use a value page.
Use value pages after that
Once the brand, casting, year, and variation are narrowed down, move into the TDG value path.
Use report products when the collection is larger
If you are working through a full garage, estate, or insurance job, a report product is faster than trying to do it by hand.
