Its just nuts what some people will do. Owning a Lamborghini also, I can tell you that when you buy one (especially the older ones, i.e Jalpa, Countach, Miura, etc.), you want to make sure that the following 3 items are a part of the sale and come with the cars:
1. Toolkit
2. Spare Tire
3. Owners Manual
There is a whole market out there for that sort of stuff! When I bought my Jalpa, I had to spend an additional $250.00 to get an OEM owners manual and $500.00 to replace the spare tire that were both missing! The only tool kits I can find run almost $5000.00!!!! Unfortunately, some owners will hold back these items and sell them later on eBay to make additional money after they sell their cars.
I'm currently looking for a Countach to replace my Jalpa with, and I can tell you that when I sign the paperwork, those 3 items will be going home with me in my hot little hands. If they don't come with the car, I'll negotiate the price down accordingly so I can purchase them elsewhere.
