Sorry, but I just don't think that's the case. You would have been better off saying "any neglected R32 will go bang at some stage", but so would most HiPo cars if mistreated and not serviced correctly.
Its far more likely you'll end up wasting hundreds and hundreds of dollars addressing all the small problems: worn out pumps, belts, and dodgey electrical connections usually surface. Then there is the ongoing consumables -- tyres, brakes, oils, etc -- not to mention fuel.
Yes you can be unlucky, but I don't think that the horror stories are indicative of everyones experience.
LW.
