Love my 06 LBZ. Have had some minor issues, but nothing out of line for a 10 year old truck with 156,000 miles. I did get caught in the few months of bad head gaskets, but luckily that was fixed by the extended warranty with the new style gaskets.
I looked at a new version of my truck the other day. Sure was nice inside, but sticker price was $61,000. I think i'll keep mine a while longer, lol.
And yes, I too get offers to buy it all the time. Just about anywhere you go where people know anything about diesels, the offers to buy it start coming in!!!
