D3 is expensive for what you get, lot of stuff over priced. Just take the car to any good vette tuner and you can do a custom package for cheaper then what D3 charges an put down more power.

 

Nope, I'll take my chances with D3. They specialize in Cadillac's. Everyone is a vette tuner, and I dont want my car tuned like a vette. Around the racetracks here in socal the D3 Cadillacs are tearin it up. I dont see any other caddies from anyone else. Plus their prices are actually pretty good considering they dont sell any junk on their site, its all top quality stuff.
