or budget-friendly models like the Used Cat 320 or 336:

• Compare Pricing: Research market rates for similar hours/conditions. Prices below 30% of new may signal hidden issues.
• Common Issues: For older 320/336 models, inspect the final drives and swing motors, which are prone to wear.
• Aftermarket Attachments: Ensure compatibility with your attachments (e.g., buckets, breakers) to avoid retrofit costs.
• Spare Parts Availability: Verify part availability for discontinued models to prevent downtime.
• Fuel Efficiency: Newer engines (post-2012) meet stricter emissions standards, reducing long-term fuel costs.
