Sorry for being as blunt as a brick in your previous thread regarding your designs.
As far as I can see looking at the stats you give, internally, your cars appear to be decent. No quality spam to be seen, so thats good. Its just that design wise, your cars appear to have been cobbled together for the sake of posting something on the forum. You said earlier you didnt want to spend much time on making cars, so instead of spending a small amount of time designing many cars, you could spend that same amount of time making a single car that looks good.
N.B an easy way of making cars look somewhat presentable is by pressing ~ on the keyboard and typing HideBuildings(). It turns the background black making your cars look presentable for very little effort
