Sounds like a good plan -- the Civic's not terminal yet! Assuming it's had oil changes, it's probably got a lot of life left in it.
I had an '89 Accord manual go to 450k kms with just regular maintenance; never needed any unusual work. Rust claimed it!
I actually just picked up an '07 Civic 5-speed with 215k kms to use as a winter car. The price was right, and I'll probably re-sell it in the spring/summer. I decided my old Firefly (35k kms) deserves some protection from the annual winter salt bath.
