Good Day!
I am hoping that I can get some advice from the forum members. I am looking to purchase a 450/560 SEL `80's model but I have no idea what to look for when I go out to test drive and examine these vehicles. Are there large differences in the models (enignes-trans-options) What are the common problems with these cars? Are these problems someone who is fairly handy with a wrench can repair in the home garage? Are parts easily obtainable for these cars? Or, should I be looking for a newer model? Though I really enjoy these body styles. There is not a dealer within 50 miles of where I reside.

Thanks much in advance!

Scott
