Hello, I'm surprised by your assessment of a rebuilt alternator, although it is true that there are those who repair them very well, I think that a new original part is just as reliable, but I think you have had bad experiences.
This brand of vehicles is very good, despite the 300 miles I think it is a great project to recover the vehicle, and if you say that in your country the parts are economical, even more, here where I live they are one of the most expensive cars to maintain.
I've also thought that it's strange that rebuilt parts seem more reliable, but after replacing many hundreds, perhaps even 1000 alternators and starters, rebuilt parts have been, in my experience, significantly better. I think the reason is that every rebuilt part is basically rebuilt to factory (or better) specifications, and then each one is individually tested. In production run parts, a factory may only test one unit out of every 1000 that they make. Many rebuild shops will also test to higher tolerances than original factory specs.
Most of the parts I order for this car actually come from overseas, so they should be cheap to maintain almost anywhere in the world, as long as you have access to global shipping. I also have easy access to used parts here in the US, because they sold millions of these vehicles here. At this point, I've already replaced many of the steering and suspension parts, so I'm expecting to get at least another 200,000 miles out of this car. Someday, I may even fix the dents and make it pretty! 😂
Thanks for reading!!
