I was actually considering making an underground garage, with a spiral ramp... But with all the other things I had to sort (some of which I still need to do) I put that idea on the back burner. Who knows I might do it later...random idea that just crossed my mind, for the layouts where you spawn at the mansion, how about having a garage there as the spawn point for car0 with reverb so you can rev the engine in neutral before heading out onto the road?
But personally I prefer starting at the steps (which will need sorting properly) then it's like you're walking out the front door, heading out for a cruise... or popping out to get some gas / petrol from the gas station. or going to a cars & coffee meet.
I was... for a crazy moment... Thinking of doing some hideaway... Like a Bat Cave somewhere along the road... who knows... maybe I did lol
