Hidden frame rust: how to spot a used golf cart that looks better than it is

Paint, new seats and shiny wheels are the cheapest parts of a cart to change, and they are the first things you notice. The frame is the part that matters, and it is the part most buyers never look at.

Most sellers are honest, and plenty of repainted carts are perfectly sound. But a cosmetic refresh is also the easiest way to hide a problem, so it is worth knowing where to look. This is especially true if you are buying for someone else, or have never bought a cart before.

Why frames rust, and where it starts

Most carts have a steel frame, and steel rusts. Battery acid makes it worse: acid that leaks or spills over time can eat into a steel frame, especially under the battery compartment. Salt air, wet storage and sitting outside add to it.

Club Car is known for an aluminum frame, which does not rust the same way. That helps, but it is still worth checking cracks and welds, and any steel parts attached to the frame.

A five-minute check

Get down and look underneath. Check the frame rails, the cross members and every weld. Do not judge the cart from standing height.
Look at the battery tray and the area under it first. This is where leaked acid does its damage.
Look for flaking powder coating or paint bubbles. These can mean rust is forming underneath.
Look for fresh paint on the underside of an otherwise worn cart, or paint that stops at odd places. Some sellers spray over problem areas to make them look new.
Take a small hammer and tap along the frame. If rust or flakes fall off, the metal is deteriorating.
Look for welds that look patched or uneven, and for bends or cracks near the welds, which can mean a past repair or damage.
Check the motor for corrosion around its terminals.

Surface rust vs structural rust

A little surface rust on an older cart is common and is usually cosmetic. What you are looking for is rust that has weakened the metal: holes, thin or crumbling steel, cracks, or a soft spot when you press on it.

Structural repairs are rarely cheap, and they can wipe out the savings from buying used. If the frame is compromised, the safe choice is usually to walk away.

Questions to ask the seller

Has the cart been repainted or powder coated, and when? Can I see photos from before?
Where has it been kept, and has it been used near salt water?
Have the batteries leaked? Has the battery tray been replaced or repaired?
Is it OK if I take it to a local repair shop to be looked at before I pay?

If a seller says no

You are allowed to ask for an inspection, and a seller with nothing to hide usually says yes. If the answer is no, or you are pushed to decide fast, that tells you something. There will be other carts.

If you are buying for a parent or a friend who does not know carts, go with them or arrange the inspection yourself. A short inspection is cheap compared with the price of the cart.
