Investment Vehicle
  
No, this is not about the Tesla IPO.
Rather, an investment vehicle is a form in which investment cash is put to work. One form might be a limited partnership set up among 3 familiies to buy dilapidated old commercial warehouses, fix them up, then rent them out and make bank. Another investment vehicle might be a brokerage account at Schwab. Another might comprise majority equity ownership in a company whose stock is then used to make acquisitions (no tax for the sellers until they sell the stock).
Lots of choices in vehicles. None of these type are electrically powered, however.
