A truly executive looking Limo I couldn't pass not modelling. I have to admit I've made the sides a bit lower and fitted with a low riding type body kit for the front and back to replicate that mob gangster type vehicle with those types of body kits they rock.
Some parts would need remodeling/optimization to make it really game-ready, but for the most part turned out happier with the topology over my older Volvo 240 Pickup model.
