Yep. After insurance wrote me a check for my totaled FR-S, I was searching the country for a manual RS 1.0, and majority were still $20k+, with the occasional higher mileage one around $18k. Ended up settling for a used Series.Yellow for a great price (which turned out to be a better decision for me).
Now you can't really find a manual RS 1.0 for under $20k -- they are also infrequently listed for sale.
I'm sure it will be a future collectible spec.
