That depends on the parts.
I've got a large truck. I haul heavy and large things. I live in the country, and no, "drive to town, rent a truck, go load it with a few thousand pounds of stuff, bring it back, drive into town, get my car or bike back" is not something I'm willing to do. Nor is making several trips with a bike trailer.
Front end of the engine (water pump, serpentine belt, thermostat, upper and lower radiator hoses) was north of $600. A set of tires is $2000. I had about $2k worth of differential work done because mine was whining pretty badly (it's spent its life towing, so this isn't surprising).
I've owned a lot of cheaper cars, and parts aren't nearly as expensive as truck parts.
