I have a 2008 Boxster with 3.4 engine and it's a great car. Yes there are risks but they are rare and can be checked pre-purchase. The IMS bearing is not so easy to check but if you are super worried, you can opt to have an improved one fitted.

Well, if it doesn't have the shaft, you can't have a problem with the bearing!
Also, you cannot fit an improved bearing to the car in question or your car without removing the engine and splitting the crank case, since both have the final big bearing.
Well, there are some who claimed to have machined the block externally to get at a big bearing, but that's pretty drastic and in any case the bearing is not the worry on the 3.4 lump, it's the bores.

Lots of people have the LV bearing fitted. Costs about £1,000 for the job.
