I would just keep it mate and try patching it up and maintaining it to a certain level...Z's are very hardy and if well maintained are good for 250K+ Mine is a June 2007 HR with 42375 on the clock and it stands on a driveway in all weathers !! Mind you the carbon vinyl and various carbon fibre bits have protected it...I don't use it all that much as I have an old Toyota Corolla Sportif 1997 which seems to be lasting forever !! However good luck with whatever you choose to do...
