Why This Search Covers 75 Miles

Small markets have fewer competing dealers. Fewer competitors means less pressure on price and fees.

CarEdge widened the search to 75 miles around Ottawa to find 10 Buick dealers with enough verified out-the-door quotes to grade. One of them is within 50 miles. The closest graded dealer is Woody Buick Gmc Of Naperville in Naperville, about 43 miles from Ottawa. Distances are approximate straight-line miles, so the drive will be longer. A dealer is ranked once CarEdge has more than three out-the-door quotes from it from the past year. Dealers with fewer are listed under Limited Data.

The best deal may be a drive away. Get written out-the-door quotes from several dealers before you go, and compare the totals, not the advertised prices. CarEdge’s guide to buying a car in another state covers taxes, registration and delivery when the best quote comes from far away.

About the CarEdge Dealer Transparency Index

Most dealer rankings come from Google star ratings and Yelp reviews — easy to game, impossible to verify. The CarEdge Dealer Transparency Index is different. We score every dealer using verified out-the-door quotes: real PDFs, emails, and screenshots from actual transactions.

Only quotes from the past year count. We split them into four groups, newest first: the newest counts 50%, then 30%, 15% and 5%.

Each dealer’s transparency score (out of 100) is weighted across four dimensions:

• Fee Transparency (30%) — Are the dealer’s fees reasonable? We add up every dealer fee and compare the total with the state median.
• Add-on Behavior (30%) — How often does the dealer include quoted add-ons like paint protection or theft deterrent, the kind you can’t say no to? Add-ons the dealer marks as optional don’t count against them.
• Price Accuracy (30%) — Does the advertised price include every charge you have to pay? We check each quote against the vehicle page: dealer fees, add-ons, the advertised price and the discount.
• Data Quality (10%) — Does the quote list taxes, dealer fees, add-ons and government fees each on its own line? Each one is worth a quarter.

Grades: A (90–100), B (80–89), C (70–79), D (60–69), F (below 60). Read the methodology →

CarEdge ranks Buick dealers in nearby markets and statewide with the same verified out-the-door data:

• Best Buick Dealerships in Chicago (71 miles away)
• Best Buick Dealerships in Milwaukee (125 miles away)
• Best Buick Dealerships in Illinois
• Best Buick Dealerships in the US

How to Use This Data When You Shop

1. Get an OTD quote in writing before you visit. Any dealer can send a worksheet by email — if they won’t, that’s a red flag.
2. Ask for a quote with zero add-ons. Everything in the F&I office is optional. Say “please remove all dealer add-ons” and see what the price does.
3. Anchor to the OTD, not the advertised price. Dealers with a gap between advertised price and final OTD aren’t being straight with you. Don’t negotiate off the advertised number.
4. Compare three dealers minimum. Even within the same metro, dealer fees, quoted add-ons and advertised price accuracy vary widely. Use this ranking as your shortlist.
