Hello Christian,
Welcome to the forum! But I am not sure what your question is about the VIN. Hopefully someone with more knowledge of European Roadster VINs will be able to help you.
Buying a Tesla Roadster as an “investment” is, in my opinion, a high risk decision. There is no way to know if in the future the car will significantly increase in value or decrease in value. I think it is likely the cars will decrease in value as it becomes more difficult to get parts and as modern EVs become continually more capable and sophisticated compared to the Roadster, which has many limitations (Note: I owned Roadster #425 for four years and greatly enjoyed the car!).
It could be a decade or more before the Roadster becomes a collectible “classic”, and during that time the car will have to be maintained, stored, and insured. Over a long period of time that costs a lot of money. And will critical Roadster parts that Tesla custom made internally be available a decade from now? Some parts are hard to get right now!
I realize my position on this issue may not be a popular one in a forum full of Roadster owners. And there are reasons to believe that the Roadster will become a valued “classic”. It could happen. As an example, I have owned three Porsche 356’s: a 1964 and two 1959 models. One of them doubled in value during the 5 years I owned it, and I sold it to buy a 2013 Model S. It paid for the S.
However, that increase in value occurred more than 50 years after the Porsche 356 was built. I did not buy it in 1959 when it was new, I bought it in 2008. From the late 1960’s to the 1990’s the car was worth about $1,000, far less than the approximately $4,000 it cost to buy in 1959. Only 50 years later did 356 values start to increase.
I hope that Roadster values increase in the future. But I would not buy a Roadster as an investment, I would buy it because it’s really cool and fun to drive!
