my dad was out in his boxster yesterday which is only 4 years old and done 8k miles when his engine broke which may result in the whole engine needing to be replaced. after a little bit of research we found out that 25% of all porsche engines break within 5 years. how bad is this for reliablilty! i think its a joke. any way this will b interesting as at the moment we are trying to find out where we stand as its only ever been serviced by porsche and has done no miles at all really.
