This is the second Grande convertible conversion I've seen. There was an orange one in Edmonton for quite a while. I have wondered why they never offered one from the factory as it doesn't take much to do the conversion and they would have looked great!
There's one in Saskatoon made with parts from a Grand Prix. The american console is strange if you've ever seen one. I think the car is badged as a Grand Prix if I remember correctly, doesn't see the light of day much.
Interesting that you should mention the engine compartment. When I first saw the ad the engine was a 396, now its been downgraded to a 350. I wonder whats going on with this car?
