Bombardier NEV or golf cart

I gave this to my dad over 15 yrs ago. He used it to run around 1/2 mi radius of home. He can no longer drive so I brought it here to Phoenix from mich. it seems to have a Gremlin in the electrical system. It will go for 5 sec at a time before (2) relays kick off. Replaced auxiliary battery. It has seen better days but is all there with the exception of one hubcap and the side mirrors. The seats are showing their age but still respectable with some TLC. Google it for more info!! I don't have a lot of answers about it so try not to ask. I have parts and service manuals. I do know where there is another exact unit which can probably be had for around $200. Good for parts if required. Price is $800 firm. I see These things advertised for $2000 to 3500. Golf cart, neighborhood electric vehicle, go cart.
