In general, it’s a really good car. Cracking to drive, gorgeous to look at and with solid reliability. The only thing is that you simply must not buy it if it doesn’t have a full service history. The XF is a complex car, and it needs to be properly looked after. Also, be slightly suspicious of that low mileage as 79k miles is pretty small for a ten-year old Jag. Make sure it hasn’t been clocked. Good starting point would be a Cartell.ie history check.
