Could’ve been a Mercedes S-Class or a Lincoln Town Car, big boxy luxury sedans from the 70s 80s and 90s. But given the fact that he co-owned a once-popular kid’s entertainment company, he was probably pretty rich at some point. So it probably was a more expensive, higher-end car like a Caddy, a Lincoln, or a Mercedes. Those are my only guesses, those are the only cars shaped like that I can think of
