yeap, the rear doesnt look that bad, im assuming it should be on road if £3000 spend..then again is it worth it?, thats the question.
Just found it; http://www.ebay.co.uk/itm/2010-Nissan-370Z-GT-326-Coupe-Grey-Dmaaged-Salvage-/261539033155?pt=Automobiles_UK&hash=item3ce4f0f043
It's low mileage, only 4 years old and still with the airbags intact but the damage to me does look pretty extensive and that's just from what I can see. It's a tough call.
Looking at undamaged examples for sale with similar mileage/age/options you'd probably have to pay around £17K at the least for them.
If you're doing work on it yourself as well so saving on labour charges then it could be a steal at the price they're asking providing you can get it up & running again for less than £4K.
You'll always lose out though at sale time price wise compared with non crash damaged examples as even if it's a great repair some buyers will refuse to pay good money for a crash repaired car.
