Any recommended reading I should do while I wait? The model history, differences by model years etc interests me.
Try this for starters: Mercedes SL500 R129 1990s History
Your new one is a '94? Don't think there were any significant changes from when the R129 launched in 1989/1990. The first big set of changes were late 1996 ('97 model year), then again in 1999.
You need to watch this of course
