If you are looking for a quality limousine service for a wine tasting expedition at a reasonable price as I was, I would highly recommend Prestige limo in Concord, CA. This is the second time I've used them in less than a year. Their communication is second to none. I've used other limousine companies for similar trips and paid as much as 25% more than what I paid with Prestige. I'll only use Prestige going forward.
