I work on cars as a hobby but I did'nt have time to fix my son's car. They had a good reputation with people in the area and the BBB rated them A+. They gave me a reasonable estimate (~$300 more then it would have cost me to buy a rebuilt tranny and put it in myself) and got the work done when they said they would. Seems to drive well. I can see why they have been in business so long. I would definately recommend them.
If you live in east Plano or in Allen, this is the place to buy beer. They have a great selection, lots of specialty and seasonal beers that are harder to find. They two men who always seem to be working when I am there are very friendly. They offer to carry your bag out to your car, offer advice on selections and pretty funny guys. Give them a try if you have a need for a brew that is hard to find.
I've never been to another Spec's, so I don't know about them. However, this location is very nice, always very clean, and well kept, and the people working there are always helpful, and friendly. I used to shop at just any liquor store, but not since I discovered Specs. After the first time I went into this store several months ago, I haven't shopped anywhere else for liquor, beer, or wine.
