That's precisely why we need a review section, so you and others can tell us what was wrong with the models. You haven't told us anything apart from the fact that they were only fit for the bin. Were they the wrong length, wrong wheelbase, wrong body…..?
If you've got the time, skill and money, you can produce very lifelike models but not everyone has. A glance at Model Railway Journal shows what can be achieved. We compromise on the likes of track gauge, 16.5/21mm, so why not with other aspects. Imagination is a wonderful thing.
To go back to an earlier question of mine, what has happened to James Mackey and his Model Irish Scale Rail? His models showed great promise but then he disappeared, apparently off the face of the earth, towards the end of last year.
