I would argue that even if you did get a used one with new batteries, you’d still face degradation down the line and additional problems that would or could be mitigated in older ice cars which are much more likely to have replacement parts available (even if those replacement parts don’t come from the same type or brand of vehicle). For instance. I know for a fact that there’s a trend of using Honda engines in older first Gen mini coopers. Buying a rebuilt engine has the potential to be pretty cheap.
