Used buyer verdict
Bennington 20 SL is best viewed as a cottage and family platform rather than a performance boat. The $37,000-$74,000 low confidence estimate should be judged against seating and vinyl condition, deck/floor condition, tube condition, motor age, trailer or lift setup, and whether the layout fits your passenger needs.
