I do not find so useful to have all the bus with their "New Look" nickname used as model just to group them together.
Most can already be found using the TDH prefix (or the few other ones like that)
There are a lot of other vehicles not grouped together anyway.
If you think it is important, we could put the New Look in chassis field. But I'd keep the actual model name as model name.
In the next version of the site (I know, when it will be done) that kind of problem will be solved anyway.
