Uh, Kathy ... I hate to disappoint ya, but ...
I always change the oil, filters, and fluids in my cars at home - always. I am also known to change the spark plugs, change belts and hoses, change out alternators, do brake work, and other miscellaneous maintenance jobs on my cars every once in awhile, as well. You're right ... it definitely has gotten tougher to work on your own car with the advent of computerization ... and the fact that they stuff so much crap in an ever-shrinking compartment! ... but I still do what I can on my own, dahlin'.
And, as for BIGBOOBS ... as you call her ... she is more than welcome to slide underneath ... uh ... my car ... whenever she wants. I'm sure she'll know what to do once she gets there, don'tcha know.
