According to the description on eBay:

We started off with an EZ-Go Golf-Cart, then stripped it down to the frame and 4 cup holders. 
You will find no cheap or plastic parts here…
The entire vehicle is hand crafted from the frame and sheet metal, including a sculpted, molded cowl, attention was paid to every detail.  
Well over $30,000 to make it runs great and cosmetic condition is excellent, along with low hours. 
It has been used 1/4 the time on a studio lots, but the rest of the time kept indoors on display.

Tech Specs:
4-link Rear Suspension with Coil Covers
Brand New 6 Trojan Gell Cell 8 volt batteries have been replaced for this sale. Pictures taken before.
