Got t-boned by a texter-and-driver on a weekend; a Halblieb's truck showed up at the scene first and towed me to the shop. I was originally planning to have my car fixed with another shop that I have used in the past, but man am I glad I gave Halblieb's a chance. Don't let the atmosphere or Scotch Bottom location sketch you out. They had serious damage fixed in less than two weeks, detailed my car to a level of cleanliness it hasn't seen since I drove it off the lot, and gave me a certificate for a free inspection (or detailing, customer's discretion) any time in the next year (which I will definitely be using). They do in-house rentals, which cost me nothing beyond what the insurance covers. Can't say the same for Hertz or Enterprise.
Halblieb's goes out of their way to save the customer money. Also, if you're not from Pittsburgh and you want to encounter a prime example of the fast-disappearing yinzer, workaholic culture, make sure you meet John while you're there.
