997.1 buying advice - Bore Scoring?

[billywhizzzzzz]

Ok, so I've finally convinced myself that I need a 991 in my life after a Z4M (although that may stay as I'm attached to it) , and am now looking seriously. However, after years of relatively robust BMWs, I'm a little nervous about the internet scaremongering around 997.1 engines - notably bore scoring and potential expensive rebuilds.

I'm looking at sub 60,000 miles (closer to 50,000 miles, hopefully less) cars - both 3.6 and 3.8 from a variety of sources.

Main questions - how worried about bore scoring should I be? And, will an independent inspection pick it up? Is there genuinely less of an issue with the 3.6?

Many thanks

Thanks for all replies - sadly I'm near Bristol so Hartech not an easy option. As I'm looking for a keeper and ultimately want a good car, I guess an alternative to an OPC is to get a car with an bore inspection that confirms no scoring but assume over the next 5 years it will need a rebuild, and when it does, get it rebuilt with upgraded components. Either that or wait a year or to and get a post 2009 997 (gen 2) once prices dip below 30k. Or buy one that has had a rebuild to Gen 2 Spec - there's one or two for sale now and these seem to command a reasonable premium understandably.

Be interesting to hear if there are any higher mileage (60k+) 997.1 cars that have no evidence of bore scoring...

The options you're considering make sense but there's no such thing as an engine "rebuilt to Gen 2 spec" - the two engines are of a completely different design and nothing is interchangeable.

That's curious as this one claims to have just that - http://www.pistonheads.com/classifieds/used-cars/p...
But certainly the Hartech rebuilds of 997.1 engines use upgraded internals - if not to .2 spec, no?
