Yep agree, I've seen much worse than that on my Granada MK1 😀

If you can't do it yourself it's going to cost to do it properly. How much sentimental value does this car have?
My Granada was bought by my dad in1985 and it's still here today after lots of work, it's currently having a bit more welding as the bodywork progresses. It's massive sentimental value to me though especially as my dad is no longer here.
