Sill & Jack point repairs to Volvo 360 - pettaw
I knew it was a stupid idea to jack it on the jacking point. OOPS The offside rear and front jacking points are collapsed and the seam has split from where the sill joins the box section.

Where can I get some good work done for a reasonable price for my old and not worth anything but still cherished Volvo?

I'm in the Harrow/Wembley area.

Very sad, but you have to take a rational view of the economics!
She may be a much loved and faithful old girl, but I fear that her time is up. Give her a decent send off to the nearest scrappy! She will cost a few hundred pounds to put right this time, and perhaps the same again next year, she may not be structurally sound in the event of a serious shunt, and you can get a good replacement for similar money!
