I bought my 2007 Plus4 some 2 1/2 years ago and I had to fix the king pins the following winter at about 15K miles. But play in the pins had first been mentioned in the car's second service at 2 yrs and 4k miles!
While I had the front end apart I sorted the springs.
The only other issues are, I've had to replace the radiator due to it leaking, but that also seems common, and sort out the rusty foot tread fixing screws.
The car has now done 27K and touch wood, it's going great. Both exterior and interior finish is good and comes up well after a good clean. For a soft top the easy up hood is pretty water tight.
Cheers
John
