Looking to Buy/Rent a Car

Hi, I'm looking to get a second-hand car and was wondering if anyone on the island has any leads - I've got a limited budget, so I'm hoping to buy at a relatively low price, but I'd also be interested in renting if that works out better. Been looking on Facebook marketplace and Autotrader, but no luck yet. 

I'm working for Poirier Custom Homes, and I'm on the island until sometime in September. 

Thanks
