The W202 has no seat mounted armrest. But, on the 1999 models, you have the problems, as mentioned, of the SRS sensor and BabySmart sensor. If you can live with the SRS system faulting and defaulting to "off", then perhaps.

Have you looked into recovering the seat? If it's leather, it's not that tough, but might be pricey.
