NADA is worthless for boat values.

BUC is closer but still off given the overheated market. Prices have increased 75-125% since March 2020.

There are several components that make up the package. Each should be considered.

Trailer - 500-2k
Hull - 5-15K
Engine - 0 - 9k

The 16 SL is not one of the more popular models so it does not get premuim values.

The E-TEC 90 is a good engine for this boat as it is light and this model does not do well with heavy transom weights.

While the price is at the bottom of the expected range, this can also mean it is in poor condition.

How many engine hours?
Maintenace records?

Is the trailer painted, aluminum or galvanized? Rust?
Tires - replaced within 2 years?

Is the hull clean, shiny? Does everything work? What is broken?
Check the transom drains, signs of leakage.

If in very good shape assuming a trailer - 10K is more than fair.
If not in good shape with trailer- 4-8K
