you mean for doing car repairs, too? like using air tools? that's the main reason i got a compressor. anything else i can use it for is just icing on the cake. example: dirty window screens? blow'em off in seconds. leaves and crap in the car vent/cowl? blow'em off.
just a consideration, if you think you'll find uses for a compressor in other areas...ie. cars...get a portable one with a decent air capacity. i got this one after reading a lot of good reviews......


if you go web shopping, you'll see a lot of compressors with a bunch of parts and lots of plastic. probably many are good, but all those little bits have the potential to break. this one is minimal in that regard. anyway, lots of options out there, but the senco is one i'd recommend. oh, and get a genuine rubber hose....not a pvc or pvc/rubber blend. the rubber hoses last longer and are easier to deal with. i guess the only problem is they come in minimal length of 25ft a lot of times. in that case, get some fittings and make two hoses. one long and one short. use the short one for bikes/things you can get close to your compressor
