The crew
Billy Wenk and his team are known for fixing what's actually wrong. Owners have come to HBI after the dealership couldn't solve the problem. We're transparent about every step and we never use scare tactics to sell work you don't need.
Comprehensive diagnosis first. No parts-cannon guessing, no repeat visits for the same fault.
You get an estimate up front and a photo report before any additional work is approved.
Text, call or email updates while your car is with us. Your choice, your schedule.

Reviews
Our 911 C4S cabriolet was loaded in HBI's enclosed trailer, transported to Mocksville for an oil, filter and brake fluid change, stored securely indoors overnight and returned the next day. Pricing was very fair at less than 50% of my dealership costs. No driving or waiting. What could be better or easier?
Sent the 911 GT3 in for track inspections because the people at the shop are track junkies like me. They picked up and dropped off on time in an enclosed trailer. The deal was unbelievable, and they treated my car as a queen. They even shared tips to run the car faster on track.
Customer service at HBI is the best I have ever experienced from automotive shops. Quality of work is exceptional. They cared for my cars like they owned them. Pick-up service is fabulous.
Purchased tires and alignment for my second service with HBI. Car picked up in an enclosed trailer and returned in the same. PCA discount on labor, great value. Billy and his crew are perfectionists and deliver nothing but excellence.
Service is incredible, the sales department is very helpful and kind, the transporter takes good care of the cars and is on time with pick-up and delivery, and the detail department is amazing at what they do.
Wonderful service and great staff. The complimentary home pick-up and drop-off with enclosed trailer is super convenient and a unique perk.
