2006 gtp lz9
Since the 3.9L motors have been around for awhile now, just curious to how reliable they are? I know GM has put them in quite a few cars over the past 6 years, but how are they holding up? Also, are they difficult to work on for service work?
Reason why I ask is I am looking at a 2006 G6 GTP to be a daily driver and it has around 70k miles. The thing is really sharp, but I am a little weary of the LZ9 engine. I have had a couple 3100 and 3800 cars, but this 3.9L engine is new to me. It looks pretty easy to work on as far as normal part replacement (water pump, alternator, spark plugs, ect). Then again anything looks easier than my North* powered Bonneville.
