It shows well, but you will have a limited audience since many will see it as a restoration candidate. To about 2/3 of the 356 buying public, anything that isn't fully restored in original spec is a "restoration candidate". Apparently many guys don't actually want to drive the cars anymore, they just want to stare and have others stare.
I would peg this one at mid 40's to be conservative. It could go higher since it's a matching numbers SC, the finest driving 356 that ever left the Factory, but I think $60,000 would be a stretch.
I'll give you a good example, I had a matching numbers Super 90 Factory Sunroof car a few years ago, re-built motor by a known builder, drove great, looked ok. Almost everyone who was interested in the car kept talking about how much it was going to cost to restore it. I was thinking $55,000-60,000, I could barely squeeze $40,000 out of it after months of looking at it. I told Matt, if we can't get $40,000, I'll keep it and drive it, at least I could see the value in a car like that.
