To answer the original question, NO.
The 300SL is a very iconic cool looking car and maybe fun to show up at a party where people see you arrive. (Like I do that a lot)
But the 300 SL, Porsche 904 or a Ferrari Daytona all are iconic, they suck big time to be in. Hard to get in and out of, especially the 904. They have pitiful ventilation, no AC and the Daytona and the SL will roast you with the engine heat unless it is 50 degrees or colder outside.
To have them in a garage like Jay Leno's garage would be perfect. Of course Jay has two real Mercedes 300SL and tons of other equally cool cars so he does not want a replica. And if Jay doesn't want it then neither do it!
