I'm actually glad to hear that because if I let my car warm up in the garage it gets a bit smelly in there. Smells just like when I used to have a garage that was 10 feet lower than the street and had to warm motorcycles up in the garage before riding up hill to the street. I thought maybe it was something with my tune making it run too rich on cold start but it sounds like that is normal.
