Graphics
Well, I look at it this way...if I am paying $25k + for an upgrade...(and I am) then I want something to show that I have a unique car. First, the graphics are not that obvious. Nobody will even notice them until they catch up to you at the next light, at which point the jig is up anyway. If you really want a true sleeper, Mallett does offer a sleeper option which removes all external Mallett Badges. But I have heard the engine and trust me, even at idle anyone that knows anything about cars can tell it is not a 4-banger.
As far as warranty goes, this is not a factory car, so to expect factory warranty is just plain silly. I know of no other custom overhall of this scale that has any warranty at all. Even the current Turbo kits offered have a minimal warranty on parts only. This is 2 years on the entire conversion integration into the platform. And it does not void my GM parts warranty. Nobody else can say that.
