The LT1 is pretty much bullet-proof mechanically. Ther have been instances where the opti has failed, and others where it has worked for the life of the engine. Like any other car, they need to have periodic maintenance. If you can wrench your own car, it is going to give you reasonable service for your dollar invested. Have a good mechanic check it before you buy it. One of the really good points is that it will save your but in an accident. It is big, and heavy, so the little economy cars pretty much bounce off of it.
There was an incident with a Toyota mini-van (at fault), the B-body wagon T-boned it, and knocked it on its side. The occupants of the B-body were unharmed. The last time I heard, the B-body was being rebuilt.
If you can find one that is a southern car (never driven in snow) you can get tremendous service from it. The engines can last up to 500K, and many have gone over the 250K mark. You can find good engines in the junk yard if you ever need one, and they are cheap...in the $300 range if you pull it yourself. Keep your fluids up and changed regularly, do your routine maintenance, and it should be a good daily driver. Mine have become reliable enough that I really do not need a backup car anymore.
If you can not do your own maintenance, find one with less than 100K and get and aftermarket warranty package. If you have a major issue, they pay to fix it.
