That looks like one nice motor, top buy mate

All this 8v vs 16v stuff i take no notice of, i have my first 16v now (after owning plenty of 8v previously in the last 15 years)
that i have owned for 2 years and not had one problem,spent plenty getting her right but as said in other replies its all about how you look after them and keep your eyes peeled for things starting to go wrong and correcting with Original parts if still available before it breaks...
On the realiability discussion there is nothing in it, enjoy the car pal, sure you will.
All the Best..
