Yes Kev,
I sold her in November 2007.
She needed outer sills and both front wings at that time.
I did not have the time or resources to restore her myself in 2007 (had lots going on at the time) so I put her up for sale and I had a caller in a few days.
The fella who bought her from me had Malcolm Fancy at Fancy Engineering put wings and sills on and someone else paint them.
The finished result looks ok in the pics now on Ebay but I didn't realise she had been sold on recently.
The problem with keeping a car like this is pretty much the same as any older car....you need a garage to keep them in and you need to use them regular.
The guy who who I sold her to had a garage but also had 5 other Fiats (no 131s) and did not use the car regularly enough so had issues with the battery, stale fuel and moisture in the points...he never dealt with these issues all the time he stayed in touch so I can only hazard a guess that this may be why its on the market again so soon

Heres a few pics from when I was assessing the rust, she had been Ziebarted from new
but unfortunately left outdoors unmoving for a couple of years before my old mate Mike Zollo rescued her prior to me buying her from him.
She was in good reasonable condition and ran ok the few times I took her out so I'd be surprised if anything serious is causing the re-sale.
