When sourcing a used buggy (UTV/ATV), you must prioritize the engine condition and hour meter reading. A well-maintained engine should show no signs of oil leakage or excessive smoke. Check the suspension system, specifically the CV boots and shock absorbers, for tears or leaks. Additionally, verify the tire tread depth and look for uneven wear, which may indicate alignment or frame issues. For electric buggies, request a battery health report to ensure the cells still hold at least 80% of their original capacity.
