My last car was a 1995 Jaguar XJ6, it was wonderful, however trunk space was an issue. Having owned 6 BMW's in the past I bought a 1998 740il on eBay. Drove the car to California from Texas, and on the way achieved between 25-29 mpg, Incredible! Both cats replaced for Calif Smog laws $2400 yikes! The car is an absolute pleasure to own, and drive. In essence its a "Sports car Limo". Fast, luxurious, smooth, powerful, addictive are just a few superlatives to descibe the car. Take care of your 740, don't abuse it, get your maintenance done when required and it will give you immense pleasure. As a side note, I later found out, my 740il was previously owned by Troy Aikman of the Dallas Cowboys.
The BMW Ride, roadholding, Solid build quality, HUGE Trunk, limo back seat space, and oh... the engine... so sweet.
I wish mine had the navigation system. Too bad the center console is not a glove box.
