Back in the 1980s and 90s I worked as an independent computer consultant. My work took me all over the east coast. For most jobs, I enjoyed driving to the client's site because it gave me time to think and relax.
Any time I traveled away from home I brought a car cover with me to cover my car while it was not being driven. During the day the cover protected my car from sunlight, birds and airborne contamination. At night my car cover kept my car dry and away from the prying eyes of potential thieves.
When I moved back to the coast of California, I continued to use a cover, but for a completely different reason. Anyone who lives within a quarter mile of the ocean must deal with salt air corrosion. Even if you keep your car in the garage, the salt air creeps in the garage, laying down a thin film of salt. The only way to protect your car from the damaging effect of the salt air is to keep it covered.
A car cover is an essential accessory for anyone with a nice car. If you don't have a garage, you need an all weather cover (water resistant). If you do have a garage, you need a dust cover.
Anyway, I feel strongly enough about this that I'm going to write a comprehensive car cover guide. Look for it in the next couple of weeks.
