I purchased this from a man who took great care of it. I was quite surprised with the power put in such a heavy car. I love driving it on this extremely hot Georgia days. Plus the engine is over 10 years old and still smooth as a brand new engine, not to mention virtualy impossible to destroy.
I would say the handling and comfort. Next would be the power (esp. after you supercharge one). Also the fact that power upgrades are quite affordable. Compare a Cool Air Induction for a newer Japanese car, you will be amazed at the price difference. It also handles wonderful for such a big car.
The interior, although mine is over 10yrs. old, it seems for such an expensive car the leather interior would last a little longer. Also the air conditioning controls (someone was slacking that day).
