How do I work out the age of my car?

Experts in antique cars such as Jay Leno give the same advice as serious art dealers and professionals in the antiques trade: Collect what you can enjoy above all because the future monetary value of any craft or art object is completely unpredictable. Still, the other opinion and plan exists: Person's living in naturally dry areas such the South Western Desert region, can approach this as a potential long term investment, due to the lesser chance of destruction of the bodies by rusting. One strategy, requires that you buy a car that is in good condition with original paint and chrome in good order. It should be purchased for less than $500 in good running condition, with no broken glass and low mileage. The car should be at least 20 years old. This seems to be the time when the value of the car "bottoms out". A person needs to have at least 20 of these $500 cars. Parked on blocks, with the glass masked to prevent wind/sand damage. No more than $100 per car per year should go to provide the outdoor storage in the first year. The cars should be started up once every 3 months. 20 cars would cost $2000 the first year in storage. By waiting 20 years, the cars might be worth in adjusted dollars, 20 times or more than when parked. Constant dollar $500 cars might become constant dollar $10,000 cars after 20 years, if long term trends continue... as 99.9% of the same models will be junked, under all normal uses... Rarity is a key basis of value, and the rest is about the innate charm of the car, and its reflection of the era it represents. A 20 fold increase in constant value is much better than most 20 year investments.
