Just get a used high end coach with the most power you can get and never look back. As per sleeves. If I spend a boatload of hard earned money, I would expect a sleeved engine whether I keep it for two years or two decades. Sleeves are an issue with me. sorry. I want a sleeved diesel.

Ok, another stupid question. Please define "sleeved".

In layman terms - Most of the larger diesel engines have a sleeved cylinder inserts instead of a bored cylinder wall. Saves on rebuilding cost. Just remove the sleeve insert and put in a new one. You are not boring the cylinder wall and installing oversized pistons which would make the engine structurally weaker after many rebuilds. Your car gas engine has a bored cylinder wall because it was not designed to go through rebuilds. And if you do rebuild it, and bored out the cylinder more, you would need oversized pistons.
