ek3 comes few different versions like exi,vi,vti,vi rs,lev, if it's a automatic one with multimatic gear box ( which have controling switches on steering wheel or neat gear lever) check whether the atf & other repairs have done on time with service history since multimatic gear boxes are very sensitive & need attention on correct time services.& check for any engine swaps as there are some exi's with v-tech engines & auto's with manual gear boxes.
also do a serach in the forum there were some threds regarding the same topic.
all the best...
