2003 Mercedes-Benz E-Class E500 Rwd 4dr Sedan (5.0L 8cyl 5A)
I still love this car, even after 6 years. Drives, handles great for a luxury sedan, and I tend to drive fast. Air suspension allows changing suspension for different driving conditions. It really works. Only problems have been electronic and happened in first 15K mi. None since; just normal maintenance. Car still looks and drives like new at 80,000 miles.
Handling, Air suspension, HK sound system w/6CD player.
Don't make the customer be the beta tester for electronics.
