A full-service collision center
Guaranty Auto Sales & Service runs a full-service collision center out of its Chestnut Street shop. The body side lists three specialties: collision repair, vehicle restoration and detailing.
For heavier jobs, the shop keeps a continental frame machine and a MIG welder on hand for special projects, and the technicians who staff the body shop are ASE master technicians.

Insurance, estimates and a rental
Guaranty Auto works with all insurance companies. Two licensed auto body damage appraisers are on site, and every estimate is free and turned around the same day.
If you need a car while yours is in the shop, the shop's own words are simple: We can arrange for a rental for you.

What backs the work
Every refinishing job carries a lifetime warranty, and the shop is Licensed, Insured, & Bonded. That backing sits on top of a business that has been family-owned on Chestnut Street since 1979.
In 2017, Guaranty Auto took First Place for Best Auto Body/Collision in the Best of the Best People's Choice Awards from The Item and The Banner, the same year it also placed First for Best Auto Repair.
