Business called Momento’s.
Different glass containers with shelves.
Different glass containers with square platforms to mount a part with another part with a frame art wall behind that tells a story about what’s being shown.
I’m getting a carburetor main body only re plated that has a shaved choke tower six pack 350cfm I believe was a 4144. What I’m wanting to do is make a square plexi glass container with a carburetor stand bolted to the plexi glass with a 2300 series 350 cfm with a story about racers shaving the horn off for more air and try and sell it for 150 dollars.
The memento business is a very small niche as are automobilia items in general. The people with disposable income for such luxury (your idea) are the "wine and cheese" crowd...aka high rollers with old, vintage cars from Rolls-Royce, Jaguar, Porsche, Mercedes Benz, etc., etc. & etc. As such, their expectations are one of superb craftsmanship, artfully executed beauty, and uniqueness.
You said both "glass" and "plexiglass" in your post. Glass is heavy, but is the better option IMO. Plexiglass is for the low-brow car brands/parts and those nice folks are "cheapsters" and don't have a lot of disposable income, if any. An option could be to use polycarbonate if you are able to heat and manipulate it into a pleasing work of art for display of high-end car parts or model cars.
All of the above requires the right "connections" to sell a product and the "product" isn't a one size fits all solution. Customers will be looking for something unique and something THEY like. You will have to work each customer on a commission basis and you have to have an established reputation. The memento product, for the most part, is not an off-the-shelf commodity. Certainly, you have heard the term "starving artist". The memento "thing" is much like the starving artist.
Question: Who makes billions of dollars every year in art?
Answer: Art supply companies selling paints, frames, brushes, canvas, stretcher strips, etc.. etc., & etc.

I can tell you like to work with your hands. A different option for you could possibly be designing and making stained glass windows, Tiffany style lamps, and the like. Again, this does require a certain artistic flair/eye to be appealing and you have to have the "right connections" and be exceptionally good. One side note on stained glass: Don't use that cheap junk sold by a lot of places. It lacks depth and richness of color, lacks interesting texture, and lacks variegation of colors (when needed).
Good luck to you.
How about posting some pictures showing recent progress on your car?
