The "SPORT" Package cars came with the sport steering wheel and BMW door sills. Only the M SPORT cars came with the 3spoke M3 style wheel and M door sills and shifter.
Very few E36s had a M SPORT package, which was mainly available on the 325is and 318Ti cars as far as I know. These are VERY rare mind you, the majority of what you seen on the market are just the SPORT Package cars.
