It’s best to show the kind of terrain you’re using so people can get an idea of what the car needs to drive over. More so “other small details” is very vague and will likely turn some away.
A-Chassis should cover what you want
That being said, if you’re not too familiar with scripting and want customizations done (as posted), I’d be happy to assist you for a much lower amount.
