Lug nuts 98 Catara

I am trying to change the brakes on my nephews car and I cannot budge the lug nuts using a 3 ft breaker bar.

Do these cars have a locking lug? The breaker bar in the trunk does not look like it should.

Thx

Called Cadi dealer and was told that they are bolts not nuts and they may have been over torked. I snapped a few craftsman on this job so I think I'll leave this one to the pros.
