I look at it as a longevity savings. I put probably the same amount of miles on my Civic as I do my Silverado each year. So that's half as many miles on my truck. Basically saved a year of driving on my truck. the $1200 truck tires last a bit longer now.
But my Civic miles are the one that's hard on my truck and the worst on MPG. Running around town, going to the store, running errands, etc. All places your trucks get door dings, carts running into them, etc. I could care less about my Civic as long as it has all its parts and it runs. Getting door dings on my 35K truck pisses me off. Door dings on my $1200 Civic doesn't bug me at all. Plus maintenance on it is cheap. No fancy oil changes for that thing. Now my truck is ready to go for long trips where I get my best mileage on it or when I need to go to the store for some lumber or haul a trailer.
