I wanted to buy before I had bought my 2.9 sierra a 2.3 sierra diesel, my friend had that car and that` s why I was conciderind 2.3 diesel. J had many times an opportunity to drive that car that`s why I can say something about it. First of all and maybe the most important thing is that it`s quite economi, it takes 6 liters of diesel oil /100 km while using it normaly. Second this diesel is really good, one can use it many years without any problems, many people say that it is much better then 1.8td. One small problem, for me it`s not a problem, it is a bit too loud inside, while it`s running cold, then specially when one is driving faster the problem disappers
