Two Generations, One Price: CAT 320D vs 320C
Two 20-ton Caterpillar excavators, both quoted on request; in-stock 320D units run $12,600 to $22,400 FOB China. One is a 2013 320D with 10,690 hours and Grade B. The other is a 2003 320C with 12,111 hours and Grade C. The price is the same; the generations are ten years apart.
This is not a simple “newer is better” decision. The 320C may be easier for a local mechanic to work on, while the 320D may have a better resale position. The right choice depends on your workshop, your market and the inspection.

The ten-year gap
The 320D is ten years newer. That usually means a different generation of engine, hydraulic control and electronics. This page does not claim a specification advantage we cannot evidence; if you need the exact differences, ask for the spec sheet for each unit and compare them with your mechanic.
What the listing does tell you is simpler: the 320D has 1,421 fewer hours, a better grade, and a much larger stock pool (13 units vs 3). The 320C is older and has a lower grade, but it is priced the same. That price parity is the question.
Why an older 320C can still make sense
Older machines can be attractive in markets where mechanics know the platform and parts are available. A simpler machine may be easier to repair without dealer diagnostics. For a buyer with a good local workshop, a 2003 320C can be a workable low-cost unit.
The risk is the opposite of the newer machine: more wear, older electronics, and a smaller resale pool. If the 320C needs a major repair, the entry price can rise quickly. The Grade C listing is a signal to inspect carefully, not a verdict.
Why the 320D may be the safer default
The 320D is newer, has fewer hours and a better grade. It also has 13 units in stock, which means you can compare several machines instead of accepting one. For a buyer who wants a lower-risk starting point and easier resale, the 320D is the default choice.
It is not automatically the better machine. A 2013 unit with a poor undercarriage can be worse than a 2003 unit that was maintained. The year and grade are filters; the inspection is the decision.
Parts, electronics and your local workshop
Before you choose, ask your local mechanic two questions: which generation do they prefer to service, and which parts are easier to source in your country? The answer may favor the older 320C even though it has more hours.
Also ask about diagnostics. Newer machines may need a laptop or dealer tool for some faults; older machines may be simpler. That difference can matter more than a few thousand hours in a market with limited dealer support.
What to inspect on both
- Cold-start video: smoke, blow-by and idle.
- Hydraulic cycle: boom, arm, bucket and travel.
- Undercarriage: shoes, links, rollers, idlers and sprockets.
- Pins and bushes: bucket, arm and boom.
- Boom, arm and frame: cracks and welds.
- Cab and electronics: monitor, warning lights and joysticks.
Who should choose which
Choose the 320D if you want a newer machine, fewer hours, a better grade and a larger stock pool to compare. It is the safer default for resale and for buyers without a strong local workshop.
Choose the 320C if your mechanic knows the platform, parts are available locally, and the inspection shows a machine that can work without a major repair. It can be a rational low-cost unit for the right buyer.
Do not choose either on price alone. Both are quoted on request; the difference is the risk you are buying.
Resale and parts in your market
The newer 320D usually has a better resale position in markets that expect 2010s machines. The 320C may be easier to sell to buyers who know the older platform and want a low-cost unit. Ask local dealers which generation they can move before you buy either.
Parts availability is the other half of resale. A machine that cannot be repaired locally is hard to sell, even if the price is low. Ask your mechanic which generation has better parts access in your country.
Inspection scorecard for both generations
| Item | What to score | Why |
|---|---|---|
| Undercarriage | Wear %, photos of shoes/links/rollers | Largest repair item |
| Hydraulics | Cold-start cycle, drift, noise | Pump and cylinder risk |
| Engine | Smoke, blow-by, idle | Major repair risk |
| Pins/bushes | Play at bucket/arm/boom | Cost and safety |
| Structure | Cracks, welds, frame | Stop-sign defects |
| Electronics | Monitor, warnings, joysticks | Older vs newer risk |
Score both machines on the same six items. The one with fewer major defects is the better buy, regardless of the year on the listing.
A note on the 320C’s age
A 2003 machine is over two decades old. That is not a disqualification, but it changes the inspection. Rubber hoses, wiring, seals and cab parts age even when the machine is not running. Ask for photos of the engine bay, the hydraulic hoses and the cab interior, not just the exterior.
Ask whether the machine has been repainted or reworked for sale. Fresh paint can hide corrosion or welds. A clean-looking 2003 unit is not automatically a good unit; it is a unit that needs a closer look.
The 320C can still be the right buy for a workshop buyer who knows the platform. It is rarely the right buy for a buyer who needs a low-risk, low-maintenance machine.
Questions buyers ask
Is the 320C available?
It is listed as in stock in China. Confirm availability on WhatsApp before you commit.
What is the FOB price?
Both units are quoted on request. Final quotes are confirmed on WhatsApp.
How many units do you hold?
13 units of the 320D and 3 units of the 320C at the moment.
Can I inspect both?
Yes. Ask for the same video and photo set on both units, or send an inspector to the yard in China.
Which one is easier to resell?
The newer 320D usually has a better resale position, but the local market and condition matter. Ask buyers in your country before you decide.
Same price, different risk.
Ask for the cold-start video, undercarriage photos and inspection notes for the 320C exy-cate320c-145 and the 2013 320D exy-cate320d-161. Compare the evidence, then choose the generation that fits your workshop and market.
