Anybody ever tote up what 'proper maintenance' per 'DM' costs? If,
including the time spent doing or getting it done, this is less than a new
engine, it's worth it. If you enjoy maintenance, it's worth it. If you
really can't afford to go out of service unexpectedly [break down], it's
worth it.
Otherwise, it's not worth it. Do the stuff that is worth it [like the
proper coolant [relatively cheap] and flushing the brake system annually or
biennially [SP?] [consequences of no brakes relatively expensive]. And run
it till it busts. Unless of course your love for your wasserleaker knows no
bounds, in which case don't buy a KIA.
FWIW
