I wouldn't,personally, consider the first one a shed. It isn't my taste but the work appears to have been done well.
I would need to see the rest of the grey Audi before passing judgement.
The Metro is a work in progress, hopefully, and most of us modders have been there.
The car with a roof rack, a bit of a mess.
The next grey car, whatever it is, is another taste issue rather than badly executed.
The yellow Audi, however, does meet my definition of a shed
Is there an accepted universal definition of a shed? For example, is this considered by the majority on here to be a shed?
