How many times do you play to tarmac the petrol station I've being doing it for while and doesn't seem..

For me, the last bit of paving the lot and street (in patches), it’s just repeating. I believe it’s just a way you can keep going back to earn more money. — I’m at the end of level 23 now, and no way to progress further. :/ (The parts don’t exist yet, apparently?) So no more need to run to the gas station for more cash now. -_-
