What to check before buying

Generation matchConfirm which generation each listing is, 320C, 320D, 320E or Next Generation 320, since engine, power and weight figures differ by generation.

Route matchConfirm each listing is the Caterpillar 320 route before comparing price, year and seller details.

Visible price and POA stockCompare priced listings separately from machines where the seller asks for enquiry before quoting.

Hours, year and configurationUse the live filters and listing cards to compare age, operating hours, boom and stick length, and bucket size.

Technology fitNext Generation 320 listings may include factory grade control and payload weighing; older 320C and 320D units typically do not.
