The full story
Why Sommer's Automotive earned this grade
Sommer's Automotive is graded A based on 5 verified quotes from December 2025 through August 2026. This review considers dealer fees, required extras, selling prices, and whether charges were clearly shown.
What they do well
- ✓ Dealer fees below the state median. Across all 5 quotes, average confirmed dealer fees were $395. The Median state fee in WI was $497, the middle fee amount in the eligible quote sample.

Where to push back
