Doesn't look like it'd need new plastic... Front panel could be repaired and resprayed for about £40, mudguard might be the same, indicator- well, minis are £15 a pair, or if you're like mw you've got the originals lying around

Something's gone a bit wrong with the grab rail, and the brake lever's almost certainly bitten the dust. (though there's still something on there)
I'd love to have a crack at it
