2002 V40 1.8i Gifted to me

[drone]

About 18 months ago I did a series of threads on fixing up a V40 that I bought very cheaply at auction for my son. It's now done over 155,000 miles.
He's now moved on and got a new car and, because of a few issues with the V40, the dealers wouldn't touch it as part exchange.
He asked if I wanted it, drove it back from London this pm.
I need to replace the near side rear door and the the n/s front wing, also the driver's door and sort a couple of minor supermarket car park knocks.
The mechanics are first class, on the way down A3/M25/ M20/ 249 and M2 if the gauge is to be believed, it averaged 43.2 mpg, prior to that, driven around London the reading was 37.6 mpg.
I want to refurbish it for my daughter and wonder where the best, ie cheapest, place is to buy second hand body panels? Son wasn't too good at positioning the car in his very narrow drive.
It's silver metallic btw.
