Not really, the M96 engine is the same design as the M97, so you still have bore scoring on the larger capacity 3.2L compared with the 2.5L or 2.7L, and you still have the IMS issue. IMS not a lot you can do really apart from buy a car having done 80k or more as generally if the bearing is going to go then it goes before then. Bore scoring is just a simple boroscope check, so easy done but definitely don't buy one without it.
So you really want a high mileage 2.7L car for maximum security against problems, but a high mileage 3.2L is just as fine as long as you've had it checked out Aside from that, there's precious little to go wrong and it's the finest sports car of it's class.
