First let me say that I am meticulous about upkeep and basic maintenance (oil changes, etc.) My Altima, with 139,000 km's (100,000 miles) on it absolutely self- destructed over the past two weeks. For no reason that I or any mechanic can find the engine suddenly (over two days) burned out all of it's oil and then scored the cylinders so badly that it needs to be replaced. I never really enjoyed this car. It looked great, but handled like a girls car. It was always sort of "dainty" and overly sensitive to steering inputs. Also, the plastic used in the interior components and the boot around the gear-stick were of extremely low quality.
The engine (when it ran properly) was fairly peppy. The trunk is a good size.
I don't care what you do. I'll never trust another Nissan product.
