Ford Festiva Car

My first car is Ford Festiva.I bought my car in 2008 November.

In Sri Lanka there are lot of ford festiva cars available.David Persis is the Dealer in Sri Lanka.After taking the car i had put a inspection from there.Also I have done a service from there.They service is good.I used to buy spare parts from New Rainbow shop at Maradana.

before buy this car some people says ford is a not good item.If you really need vehicle buy a Toyota or Nissan one,but not Ford.In Sri Lanka famous brand for vehicle are Toyota and Nissan.

But during the past years usage i believe ford is good brand.Ford vehicle are durable ,not like Toyota or Nissan.

Also Ford festiva's fuel consumption is good.I can go 15 kms per liter outside the city limit.

I want pass the message that Ford Festiva is not a bad vehicle.It's really good.Buy one and see the different.Do not think Toyota or Nissan is the only option.
