real dumb question but i nee to ask

i know that a car is ment to be driven but its been really nasty weather here for awhile now and im so anal that i will wash it completly before putting back in the garage which means right now i would be washing it every time i drove it

question: if it sits in the garage and i start it up once a week and let it run for awhile and blip the throttle a few times not over 4k rpm's but after its been running for about 10min and warmed up,, is there anything wrong with doing this as far as pre-mature damage or muffler rot due to sitting for a week at a time

i know this is by far the dumbest question i have asked and i have asked some bad ones but wanted someone elses thoughts on it

It would be better to hook up a battery tender to it and LEAVE IT ALONE until the weather gets better.

It is not good to warm engines purely at idle. Also you can't get enough heat and keep it hot long enough to drive out all the moisture, and when you shut it off, the engine draws in more moist air as it cool making things worse. And for the exhaust things even are worse since it takes longer to heat it up to dry it out.

Leave it alone until youare ready to start driving it.

If you don't mind my asking, what's nasty about the weather in Texas right now? You don't have snow and salt on the roads, do you? Is it really just rain you're trying to avoid?

I believe you would be far better off letting the car just sit. As long as you run the car once or twice a month, it should be fine, even without hooking up a charger. The important thing is, make sure you drive the car for 10 - 20 miles so everything is heated up and all the moisture gets removed.

I would also suggest leaving it in the garage on full tank of gas, to avoid moisture building in the fuel tank.
