If it is truly a corporate investment, then the OWNER shouldn’t HAVE it - the car should be owned by the corporation (legal title, registration, etc). However, I suppose there is a way around that - a trust declaration for beneficial ownership, such as discussed here:
As long as the shareholder doesn’t benefit from it (personally), there shouldn’t be an issue. However, if the owner purchases it personally (without corporate funds), he may be able to sell it as a used, personal vehicle, and there would be no income tax on the profit.
