Our 2004 Colorado smells

[fldagirl]

It has smelled since the day we purchased it. Not a new car smell.

We thought it would go away but the warm weather only seems to make it worse.

Any advice?

Thanks

Does it smell like rotten eggs ? if so have the catlitic converter checked for leaks. and look for oil leaks in the eng compartment both cause a smell in the cabin.
