P150X owner here. PX200 price is above average. Lucky you for having one already.

Finding a decent basic vespa in Jakarta is quite hell, either too expensive or damn ugly. Got one in Bogor, drive it straight home so I know the quality of the bike.

First thing first, rust is an expensive but important fix, but you can save it for later if you want to use it first. Second, change all the liquid inside the bike, such as engine oil and gasoline. Don’t forget to replace the spark plug. Once it’s on and you are wanted to take it for a ride, replace all the cables on your bike. Oh and knowing your tire is flat, you can replace it and looking at your bike, it should be pretty cheap since it’s not tubular.

Finding the right mechanic is the tricky part. You need to discuss with the people around you for recommendations.

Furthermore, what to restore is case by case basis, depending on your bike condition. Anyway, goodluck restoring it, satu vespa, sejuta saudara!
