Really of the 2 options that are available in JC, Trinty ranks the highest for me. The only problem is they are short on drivers and cannot sometimes meet the demands of peak times like end of months, Friday nights and holidays. Their employees are by far the most nicest though and the fares are reasonable for the most part depending on who you get as a dispatcher. They remind me of the old show Taxi sometimes.
Use Trinity!! I rode them for the first time today and was totally pleased with the service! Very fast and quick response both phone and driver. Polite driver, air conditioned car! The fare was so great, cheaper than I had expected!! I'd use them again and recommend them to everyone!!
