The annoying things for me is you can't find them in junkyards anymore and BAT has ruined their pricing. Now every piece of shit is a few grand when 10 years ago you wouldn't have been able to give it away.

Who is scrapping an E30 for minor problems now? I haven't seen one worth saving in a junkyard in years, all smashed up or completely rusted out. These cars, being unibody cars with more advanced construction techniques, aren't going to be as easy to save with severe rust or body damage as the crazy muscle and prewar classic car restorations we've been seeing in the past couple of decades. They aren't yet rare or valuable enough to motivate people to spend tens of thousands of dollars on fabrication and body work in any large number.

I saw this happen with BMW 2002 cars when the newest of them were only 20 years old. I used to pick them up for 200-300 dollars in the late 80s-late 90s. Brace yourselves as it will not get better. The good news is that the E30 holds up to rust far better than the 2002 did and are relatively plentiful after 28+ years. In my experience an E30 still lasts for 5 years after the rust has set in and started. This is not the case with many other cars. I remember when a Subaru (and other makes) would start to rust and by a year later, the thing would have terminal rot. Could be a LOT worst depending on what you like to work with. Anyone up to building a body jig...

Technology will eventually fix that issue. Once large 3D printers capable of printing car shells become affordable enough, which will happen in the future, then you will be able to 3D print your own E30 shell (or any other classic car shell for that matter) for pennies on the dollar. You can even print out all the parts needed to build an entire car. We're still at least 2-3 decades before that reality however. In the meantime, the existing pool of clean E30 shells should be enough to last for another 2-3 decades.Last edited by varg; 02-03-2020, 08:15 PM.

Eventually, just not in your lifetime. Similar to how you can't use a plastic 3D printer to reproduce a 2L bottle just because it's plastic, there's a lot more to the structure of a car than "it's thin metal" and additive manufacturing processes have limits. 3D printing with metal is just sintering with a laser, sintering is not a new process, even doing it with a laser, layer by layer, is not new (the SLS process was invented in the '80s) it's just nearly mature now. Unless you're going to print atom by atom for direct control over the structure of the material it is not possible to replicate the qualities of worked sheet steel with a deposition process like laser sintering. To do so would require what is essentially a replicator from star trek. By then you'll be living in a simulation and might be able to code yourself an E30 shell matrix style. Large scale atomic deposition printing for replicator like capabilities? Basically the holy grail of manufacturing. I'll print you a gold cylinder head when I see that happening... you might have to print yourself an exosuit to carry it though.
It’s often assumed that components in additive manufacturing are only made of plastics. Wrong. For example, in DTM vehicles the water pump wheels used are made of an aluminium alloy. This part – made using 3D printing technologies for metal – is very important for demanding race conditions.R135 /// 1990 Alpinweiß II 325is

I cannot see a large 3d printer doing a metal car bodyshell even in 50 years as I think it would run in to strength versus weight issues, which is where bonded sheetmetal really shines as it can be made stong in multiple directions with relatively low weight assemblies. Perhaps we could see nonmetallic bodyshells.
