Why don't you buy a canary?

My Nissan Frontier pickup has a cracked exhaust manifold. This means that exhaust gas can leak out between the engine and the muffler. One of the main components of this exhaust is carbon monoxide (CO). It is odorless and invisible. Nut cases who want to commit suicide park their car in a closed garage with the engine running and die. The person doesn’t   feel a thing; they just pass out and quit breathing.  

I’ve decided not to get the problem fixed immediately, the bill would be $410. My temporary solution is to drive with the truck windows down this summer. When it rains I’m going to take the CO detector from the bedroom and put it on the car seat beside me. When I explained this to Janeil her response was, “Why don’t you get a pet canary instead to ride with you? If it passes out before you do, you’ll know you’re in danger.”  

She would really like me to sell the pickup. When I checked with KIA Nissan here in Corvallis they weren’t interested in buying it at any price.  They said it was basically sound, but that it would cost them too much to make it “pretty enough” to sell.
