My mother had a new 99 E320 in the same color. I would try and sneak it out whenever possible. Of course that was the first year of the infrared starting key and it was sometimes glitchy and not want to start the car, leaving me stranded where ever and with a mild panic attack. I don’t know about the E300 trim level, but the 99 E320 was the first year of the V6, and it came with an “all leather” interior instead of just seating surfaces. It had the newer fiber optic connected CD changer, Bose speakers, and the head unit with the cassette player hidden behind the LCD display. It also had side curtain airbags, the extra wood right around the shifter gate, the aformetioned infrared key and associated updated alarm system, and little things like the redesigned trunk release button in the center console that had to be lifted up for a couple seconds instead of simply being pressed, so as to avoid accidentally opening the trunk.
