Same here, I'm sure they could've, at least, tried to hide it, but it clearly wasn't a concern (there a sequence were he's wearing a short T-shirt and the camera angle even allowed for the belly to be seeing from below).
He did leave them a more pricey car, isn't it?
One of those coincidences, do we know if he got the opportunity to see the end product?
That's a summary I can get behind.
