That one is very nicely done! Interior is especially nice and fits the model.
The 359 replica has a longer wheel base than the 356 replica - the pan is cut only 5" (not the 10-11" for the Speedster). That gives a huge engine compartment area. Many came with the hard tonneau (seen on the red car show one). These kits sold for $14k back in 1989-91 and only 210 (?) or so were made. Thunder Ranch also bought a couple and finished them as prototypes. There are 2 out there with 3.6L Porsche engines in them (Japan and NY) and one with a Mazda RX7 rotary engine.
The $895 CMC windup windows were an option for the 359 too! Shame they didn't make removable 911 style hard top of it (great project).
Not a lot of info out there but they are rare (and many think that's a good thing).
