Astarita Car Service
 

Has anyone heard of or used this company? I got a good quote from them for a tour of the Amalfi Coast but the only reviews are on TripAdvisor, and mostly from people posting only that review soon after signing up on TA.

I know this company. Me and my husband used Astarita Car Service for a shore excursion in November 2010 from Naples Port to the Amalfi Coast.
You'll find reviews just on Trip Advisor because they are a new Car Service Company...I was a little bit worried as well when I booked but when I saw the driver Antonio (really professional) and his perfect vehicle I've been really happy about my decision.
Everything has been perfect and unforgettable! Everything written on Tripadvisor.com is real! Don't worry about reasonable prices they have! We checked a lot and are not cheap but REASONABLE!
We really suggest http://www.astaritacarservice.com/
Check reviews also on their website.
