Are you kidding?
I went to the wrecker next to the hardware store; not only were they overpriced, they were VERY rude. And a lot of my mates experienced this too.
As I drove up the road, I found these same guys you wrote about and they were as professional and helpful as I have never experienced in my years of 'playing' with cars.
Since the first experience I have always gone back there. And so are my mates also into cars.
All the guys I know rave on about how friendly, professional and helpful they are. their prices are awesome! Even when they don't have the part, they go the extra mile to assist you. And this is not just me talking, my mates also say this.
I will recommend them any day to anyone!
