ive had 2 saphs,1 which the chassis leg was welded and it was such a good job it was hard to tell,the next were mint but patches on front floor,then 3 door,in which had sat off road in a drive for 5 years,and i couldnt believe how clean it was underneath,chassis legs solid,all it needed was a very small patch to 1 side of the boot in which u cant see from inside
