97 was the last year - 98 was just SL500 and SL600. It's an interesting run - 94 to 97, some changes every year. 94 was the last year of no standard traction contol. I believe 95 got ETS traction control standard, ASR optional. Then 96 got ASR standard (I think), new interior, monocromatic paint, and other cosmetic changes, but still had 722.5 transmission, then 97 got 722.6 transmission. 96 and 97 are not supposed to have wiring harness issue. 95 to 97 are OBDII diagnostics. Being a caveman I'd look for a 94 without traction control or a 95 with ETS.
