e21 potential purchase
So Im new on this forum.. but I've been looking at getting an e21. BUT I have one problem with this car.. the current owner says that the left side front frame rail is starting to sag... im not entirely sure what he means.. but is this a common problem with e21's? is it just rusty? I can weld in reinforcements.. but i would have to drive it about 500 miles before I can fix it.. should i take the risk?
