Bill yeah that frame section looks to be nearly gone (not just rusted). For the right price and if close by would not be a deal killer as it is fixable. But better to let someone else deal with it. Though those grills are very desirable but IMO this one not so much. As for slow heating could be anything. Many times like others have said it's die to using the tank valve to turn off the grill leaving the knobs on and than reopening the tank valve to start it again. Trips the OPV device.
Best thing then is turn off grill and tank, disconnect the tank wait a few seconds. Reconnect the tank, turn the tank valve on slowly. Than turn on the front burner only light it and continue turning on the remaining burners.
Unless of course there is a physical issue with the manifold (really odd and rare) or there is physical issues with the burners (very possible) especially if it's the crossover burner
Keep hunting
