First off Is this a $20 k driver or an alegedly $$$ show car ?
Not to start the flange or no flange argument , this is a correct looking flanged panel joint . imo
It look like whom ever did the work took attention to detail in sealing the joint end and getting it cut straight.
Is it a car show winning repair no. But at least it's not hidden totally hack repair that will show its ugly head.
They. Seem to have taken some attention to detail , except for the tape holding the lug wrench to the jack.
The only thing that is an unknown is if the flange joint was assembled correctly weld thru primer behind and stitch welded correctly . Only the one who did the work knows .
