well I think it is very much a luck of the draw thing. bought my car with 62000 and two days later the coolant light came on, the plastic intake manifold had started to leak. I got that fixed and a few weeks later the brakes trashed out on me and then ate the rotors on the front, so I got all new brakes. a few months later I am on the highway and the belt tensioner pulley bushing went and I lost the belt so had to get that replaced. one year later, almost to the day, I was getting off the highway and I heard a knocking. looked down and I had 0 oil pressure. turns out I threw a rod bearing and then the rod cracked the block. now I am breaking in a whole new engine on the car. I changed the oil and filters every 3000 miles or earlier, and don't really beat on it.....I have my camaro for that. if I didn't like this car so much I would have ditched it a while back, but it is a very enjoyable daily driver.

Holy Crap! 
Looks like Bonnevilles are notorious for throwing a rod bearing and cracking the block. Best be careful then, yeah, you're right, it'* luck of the draw.

93 SLE is right on. These motors are strong. Just make sure you keep
and eye out for any oil contamination from a failed UIM. Rods through
blocks are NOT common on 3800'*.
As with any other motor, if you take care of it, it will take care of you.

If anyone ever has a chance to look at a few Bottom ends....
Look at the 3.0 Buick V6 HO 85-87, 86-88 3.8 HO and any 3800, then take a look at a few others like a ford 3.0 60* or 4.0 60* among a few other makers.... And you'll see the diffrence
