I'm going to have to talk to you about taking pics!!
That is certainly a first for that wagon, at least since 2005. It doesn't have the hottest heater. I was going to change the thermostat but it was something I never got around to.
You might check the firewall/footwell on the driver's side. Sometimes I got a cool wind on my feat there. Might be speedo cable grommet isn't seated.
It is the best driving/running W123 I've ever driven, and I'm glad it has gotten favorable remarks from you, Tyler and Colin. I was of course biased, but then again, I've had quite a bit to compare it to.
I look forward to following your ownership experience. Not one time did that car ever leave me stranded, and really had very few hiccups of any kind. I found a really nice interior, front and back, and with the paint job Tyler applied I bet it represents the brand well.
Enjoy that thing, and I'll be stalking your ownership experience!!
