My apologies if this bump gives you false hope, but I feel I should explain why I'm not going to take up this suggestion
It took many hours and compromises to make a remotely blockland-appropriate version of the Crown Victoria's rear end.

This level of smooth curviness is what made me decide I'm going to stop replicating real life cars
and this...

...I choose not to model.
Sadly the early 2000s were not a great time for non-curvy vehicles. I went ahead with the Crown Vic since a) my brother has one and b) it's super iconic as an american taxi / police car. sadly I just don't have enough of a reason to deal with the sentra's level of roundness. (at least, not while I have as many planned projects as I do)
