Hey Will thanks for looking at my Mercedes! Your LM car is cool i like the opening engine bay and the detail on the engine. Answering your question yes this would more than easily fit...you could build another 19 or more LM cars and they'd fit in the back too :-) The Mercedes is 105 studs long and 22 wide, it's a Monster of a Mercedes. I'm building the Porsche 917k at the moment (16 studs wide) four of these will fit in the back. Keep on building Will, you've got talent!
