Oh no... this is enlightening. I Googled "Pro-Touring" to see if I could get a better description than, "A car that handles, stops, and accelerates with modern performance cars, or better. Usually have some creature comforts". That description makes Blues GP a Pro-Touring car... congratulations.
This is by far the best description I could find in under 2 mins.
"a protouring car is basically a hotrod. A car that has been lowered, has 20" billet or 3 piece wheels, preferably which ever is more expensive, has smoothed body and the latest parts including fuel injection, turbo chargers, and baer brakes are mandatory preferably the biggest ones you can get. A custom interior is nice and it must have at least some new suspension pieces, doesn't really matter if they work good, but they need to be new and tig welded, and probably have polished billet coilovers.
One must talk about going to the mystical place called "the track" you must always mention that when thinking or talking about the car in question. However it is not required to actually go, but when building it, always ask yourself if whatever part you are going to buy will make it look more "racey". If you want to see the top protouring cars, going to the "SEMA" show IS mandatory, these are the finest examples of "protouring" cars. Mostly ex-hot rod builders that put 100,000K plus into the cars to create on off special machines that are kept stowed away or sold on ebay."
With all that being said, and quoted lol. I am too still waiting on "Pics of this work of art under aforementioned Silverado."
