Scawen, modifications are an "addition" to the game. They are installed for their own use to be able to see something other than the serial model in the game. Nowadays there is such a trend that mods (e.g. vehicles) are better used for 'fun' than what the game creator gives. Sorry .. this is not 2005 or another .. These are times where people need new products, something that will allow them to change their existing playing for something more ..
To yesterday's topic regarding the modified VOB .. The development team should clearly write that it allows to insert VOB mods, but with modifications of the original models ... (diffusers, additions, other steering wheels, other lamps etc., custom gauges for Lazy Dashboard etc.)
Nobody wrote THAT VEHICLES WITH A REAL BRAND CANNOT BE ENTERED (I mean Honda, Nissan, BMW, Porsche etc.)
