I had one (a late 2009) for about 4 years. A 3Dr, on factory 18s. Really good car, not very exciting, but it was really lovely to drive, never, ever let me down, all I put into it apart from tyres/pads and oil/filters were front wishbone bushes (once), a bonnet catch (they seize) , a steering arm.
I drove mine somewhere between brisk and hard all the time, never had a problem with EGR or DPF or Cat, but I did put a good fuel treatment (BG) in regularly.
I miss it tbh. Lively enough to keep up with most normal cars, super comfortable, tidy handling, rattle free and between 50 and 60 mpg.
