Looks good. Part Ghia, part Opel GT to my eyes.

I wonder if it has the original Solstice engine or if it has been modified/upgraded? Hopefully modified/upgraded.

More info and photos from the owner:

As requested, here’s a bunch more pictures of the build. The body is made from epoxy resin, fiberglass and some carbon fiber. No kit, no molds or plugs, it was all made using techniques I’ve been developing over the years. All body filler (pink stuff in the pictures) is custom made epoxy based filler (no standard bondo/body filler was used). It took me about 18 months of nights and weekends to finish it. The gauges are from Dakota Digital with faces they made custom for me.
