You'll sell a few of these kits. 
In fact I wouldn't be surprised if a 996 converted like this becomes more valuable than a standard 996.
I've been thinking about a 996 as my next daily. My kids are grown so I don't need the room of a four door anymore.
The only thing holding me back was the reputation of the engine.
Porsche has always maintained that only a small percentage had the problem.
Well if this is true why didn't they recall that small percentage and fix the problem?
There are lots of people all over the planet making a living repairing this "small" percentage.
(A small percentage to me means less than 5% of cars are affected)
I'm not sure this conversion is for me but at least people with ailing 996s have another option now.
Meanwhile... I bet a new 997 would have trouble keeping pace with this car.
