Mike, as for the straight mechanical stuff: Not too surprisingly, most of this stuff can be had at Canadian Tire. Some parts on the DSMs are identical to other, much cheaper, manufacturers' parts. An example I remember is the thermostat: the thermo for the Hyundai (Elantra? Sonata?) is the same part, about $180 cheaper.
Maybe you guys remember some more cheaper comparisons to help Mike out...?
