They do Isuzu repair.
After an hour on the internet and 2 hours on the phone Firestone was the only place that thought they could fix my car besides Ultimate Isuzu in Fredricksburg (and I was afaid to drive that far). 3 hours and $300 later my car was fixed. Not only did they diagnose the problem quickly but they had the part to fix it. All of the employees were very friendly and accommidating. They let me plug my cell phone in so it could charge while I waited. I would definately take my car there again.
