Caterpillar 320 price
Budget roughly $230,000–$270,000 for a new machine before attachments, delivery, and financing. Used examples sell for meaningfully less depending on hours and condition.
New vs used & financing
Buying new gets you warranty, financing incentives, and top resale; used saves roughly 25–45% if you verify hours and service history. See our financing guide for loan and lease options and Section 179 tax treatment.
Rent or buy?
If your utilization is below ~60% (under ~12–14 days a month), renting usually costs less — check live rates and the break-even on rentd.
