that's a can of worms there !!
nothing before 96 the older carts can be hard to find parts for
all carts have a following... i like the Ezgo TXT electric 48 volts ... i find it to have the most after market stuff
it also depends on your ability
If you can tear down a lawn mower and put it back together i would say gas cart
tell us what you are wanting it for ,... going to the deer stand or off road riding , street cruising ??
