Definitely hot pink or lilac
Seriously though, I don't see too many red golf carts, so "resale red" might not apply to golf carts? If you're wanting the color that appeals to most people, go with neutral colors rather than bold. If you're painting a fully customized cart, bold is the way to go.
The colors I see the most are, in this order:
Stock colors:
white
green
blue
Custom painted:
silver
black
medium blue
grey
orange
local team colors
Wraps:
camo/mossy oak
blue lightening
red flames
