I live in northern Arizona. This is the second big job Tony and his crew have done for me.
Tony, Tom and the Callas Rennsport (CR) crew have just completed a PPI on a 2011 Cayman S I am/was considering for a purchase (I actually did pull the purchase "trigger"). Now, my sense is that work at CR is not inexpensive, nor is it "cheap". What do I mean by that?
Well, if you want a quick once over PPI, just to identify any obvious (obvious to a skilled technician) problems, you best go elsewhere. That is not what CR provides. They do the work necessary to identify just about any and every issue the car has. CR is for the car you plan to keep for awhile, and do not want to become a bottomless "money pit". At the end of their work, you will know exactly what you are buying. You will know whether to walk away, renegotiate the price and/or smile with the satisfaction and peace of mind of knowing exactly what you are buying.
On the other hand, if you are a gambler, there are many "cheaper" alternatives for a PPI.
