What products did they have before Elon?

Yeah and who knew about it? Nobody.

Before Elon Tesla was 2 guys with a piece of paper saying 'we should build Electric cars'.

Elon provided most of the funding, and it wouldn't have gotten of the ground without him.

Next Eberhard ran the company straight into the ground and Elon had to take over.

Then Elon had to invest even more money to save the company.

From there he made it one of the most valuable car companies in the world.

Thus, anybody who thinks Tesla would actually exist without Elon is just a fool.
