Hey welcome to the world of FTO!
There's loads of people out there that moan that the FTO is an 'Import' and you can't get anything for it which is totally untrue.
If you're tappets are noisy there is more than likely nothing wrong with the car as it's an 'Achilles heel' with some of the V6s' If you have a GPX Mivec model they can be adjusted with a bit of work.
Good quality fully synthetic oil should be used when doing an oil change. Some people say to do an engine flush before but I never noticed any difference to be honest.
But tappets usually should quieten down after 5mins or so after cold start up, can be a wee bit embarrassing sometimes!
If you have any other specific enquires don't hesitate as there are lots of people on here that can help out or point you in the right direction. One thing I would check out is the condition of the timing belt (as in all secondhand cars) and get it changed if necessary.
The FTO is a great car and very reliable
