When my car showed low tire pressure too frequently, Paul I advised I should have it checked. When it was checked it was discovered by competent service staff that the tires were so worn as to be unsafe. Darrell K sought me out with a quote for replacement tires and advised that there was the potential for a blow out while driving, so I should avoid using it as much as possible. He helped line up a loaner vehicle for me so that on the day my tires were replaced I was able to make it to my scheduled appointment in the Twin Cities. During the course of the repair I worked with both Connie M and Paul, and the cashier, who checked out the loaner to me. Darrell put together paperwork so that I could apply for a rebate on the tires. Needing service is always an inconvenience, but the Heintz staff does a good job of making it as painless as possible. I have worked with all the service staff, and have never been disappointed. Thanks!
