So, Lnd Rovers have always had aluminum panels. Unsure of the smallest one. Many vehicles have aluminum body parts. Miata's always have had aluminum hoods. Had a Citroen (no, not a candle) many years ago. Some parts of the body are aluminum. Audi A8's have been aluminum for many years. TIG welding aluminum has been around a real long time. It used to be called heliarc. There are even MIG machines for doing it. Just takes a shop wanting to do it and getting people certified for it.
The metals in modern cars are not your basic low strength steel, haven't been in a very long time. They are light weight, high strength steel. Repair requirements are very specific: certain areas must be replaced, not just a piece cut out on most vehicles, and using so much heat in certain places, etc. Very procedure oriented. That's why your insurance company may require a certified shop do work (not a specific shop, just certified).
And we will be seeing more and more aluminum in vehicles as the current administration increased the CAGE requirements. Aluminum based parts shouldn't be priced much more than steel parts -- the commodities market has been flat for quite a while (right in line with the price of crude oil, surprisingly). ALCOA is splitting in two, with one part being the mining and raw aluminum business (now the poor stepchild) and the other the specialist metals (largely aluminum) and parts business. I do expect the commodity/volume auto manufacturers to go through some building pain as they get there processes to work (remember the low VOC paint change over?).
