Upgraded Seat Cost

[Accountable1]

I am new here and will be buying my first golf cart in the next month or so. I really like the look and feel of Yamaha carts and it will likely be a few year old. I am trying to decide if I want to buy a cart with no upgrades ( rims, backseats, and aftermarket seats) or wait for the right one with those items already on there. I am just trying to get ballpark figures on the upgrades and the only one I cannot find real info on is the seats. What would the cost of upgrading the seats to something like LazyLife seats be for both from and back? Thank you in advance for your responses and if this is the wrong forum just let me know and I will move it.
