Buying From Mike Haggerty Buick GMC

Mike Haggerty Buick GMC sells new Buick vehicles and usually takes trade ins, so its used lot is a mix of brands. A certified car from the brand program comes with a factory backed warranty. A used car that is not certified is sold on the same terms as any other used car, so read the window sticker. How certified cars work.

Whatever the grade, the grade is about the dealer. The car is its own question. Ask the dealer if an independent inspection is allowed before you sign. A good lot says yes.

Common Questions

Is Mike Haggerty Buick GMC a good dealer?
Mike Haggerty Buick GMC earns a C in the PPI Auto Buyer's Guide. Mixed. Many buyers were happy, but a real share were not. The grade reads 1,254 public reviews averaging 4.2 stars, with 16.8 percent at one or two stars. It rates past buyers' experience with the dealer, not any single car.
Can I get a car at Mike Haggerty Buick GMC inspected before I buy?
Yes. PPI Auto sends an inspector to the car on the lot in Oak Lawn. You do not have to be there. The inspection covers 122 points, a full OBD-II scan with readiness monitors, a road test and photos of anything found, and the report comes the same day. Ask the dealer to hold the car while it is checked.
How is the grade worked out?
It needs 20 or more public reviews. The star average is pulled toward the national average by 25 average reviews so a short record cannot jump the line, and the share of one and two star reviews sets a ceiling. The full method is on our grading page.
Is Mike Haggerty Buick GMC open on Sunday?
