2010 Mazda MAZDA5 Sport 4dr Minivan (2.3L 4cyl 5A)
I have two of these and I use them as taxicabs. I have a fleet of 14 cabs and have used Subaru Outbacks, and Volkswagen Passatts. We put about 50-60,0000 miles a year on each of our cars. The VW's cost me about $4,500 a year to maintain and the Mazda's cost me about $1400 a year. The car is solid and well built in my opinion. I'm gonna buy ten more once the VW's all blow up their engines, which I know will happen since almost every VW Ive had blew up after around 150,000 miles. Highly recommended.
Reliability. Smooth drive. Great visibility. Similar to European style mini-vans. Great fuel economy. Simple technology.
I can see how power doors would be helpful for some, but in the taxi business, that's probably just one more thing that would need to be serviced.
