SHEESH - That's a dream line up you have there sir!
Thank you for your input as well. I am definitely going to be asking for good clear photos of the undercarriage and all VIN's.
Also for what it is worth I will add - I am looking forward to having an ongoing project like that as well. Finding something that is really clean, everything works, and over time I update and refresh OEM parts to new. It will mainly be a weekend car for the lady and I to just enjoy cruising in, but can also be daily driven if I choose to and could even see a track day or two through the year. Essentially a mostly stock car with a few small upgrades that make it fully capable of being driven a little harder once in a while.
The E36 is for for sure at the top of my list, but the the E46 M3 is right up there as well. Its just a matter of finding the best/cleanest manual M3 of the two that I can find within my budget.
