The heater hardly works without the shrouds on. You will get a little 
heat, but not much.

Warm ups take longer which isn't good for the engine. This isn't much 
of a factor in the summer, but is in the winter. If the car is only 
driven short distances, the oil will never warm up in cold weather. 
Don't forget by "warm up" we're not talking cylinder head temps, we're 
talking about getting the oil warm - hot enough to get rid of 
contaminants etc.

Also, when you drive through water, you'll get a lot of moisture blown 
into the car if you have the heater or defroster on. If the defroster 
is on this will show up as condensation on the inside of the 
windshield. If you have air conditioning you can turn it on and use it 
like a dehumidifier or defroster, just like new cars do.
