Thanks for the insight. I'm currently looking at one iswara 2006.
1 lady owner w/o modifications. don't know why people target lady owner cars. from my experience of buying a second hand car lady owner, and my own mom's car (2 of them in fact in which i inherited the iswara)
no. just f***ing no. i have to clean up their mess just because they think its fine to leave an mineral engine oil in the engine for a year as the mileage haven't reach 5k. or like wise replacing out of spec air cond system/parts, never flushing brake fluid, never flush radiator coolant...
and the list goes on. women, GENERALLY (obviously there are some exceptions, hell there are even some girls/woman that are active in motorsports) have this rule of thumb: so long the car can move, don't fix it. the concept of preventive/regular maintenance is almost non existent.
now for your issues:
generally as da best one mentioned (which for the most part, are CHEAP solutions, and its surprising how most people can't perform even low cost/cheap maintenance properly

): hoses
any cracked/leaking/loose ones, replace them
spark plugs, cheap and cheerful, few ringgit. and don't forget to inspect the used spark plugs! then you can determine if your engine's running too lean/rich and can tune AFR without a dyno + wideband sensor
mountings are also cheap(even for original ones), and if they are broken, replace. no questions asked
of course, try to replace mountings AFTER you solved the other issues, so they do not deteriorate your new mountings faster than they should
to add on to
dabestone:
i'll assume it is a carburetor engine ya? if so, check the idle rpm, both with/without air cond idling.
secondly, consider spending rm45 to perform carb cleaning
and more often than not, woman will neglect on replacing the car fluids/lubes such as engine/gearbox oil, replacing those may just solve most of your problems
