I think the model 3 performance is more closely compared to a BMW M3, or Mperformance 340, not the 5. As to what the Model 3 will lose in depreciation over the next 3 years will depend on what other manufacturers (or Tesla) brings to market in the next 3 - 4 years. Tesla will bring the Model Y which will compete with the BMW iX3. Based on the interior quality and fit and finish of Tesla, if the BMW gets equal range or close to it, Tesla will have some competition and used car prices will reflect that. BMW has some elbow room, where Tesla says it is limited by needed cash flow. So, the model 3 doesn’t have a lease program (and there I’d no lease program in my province at all) snuff that may be the same with the model Y. So, BMW will do what it does: artificially high residuals with attractive lease rates available in all markets, to bring the monthly payment down. As I staid, it difficult to predict what any EV is going to be worth in 5 yards from now.
