Hi,
For Colombo the people near kalubowila, I have a good baas who has a very good knowledge. In front of Kalubowila hospital there is a road called Peris road. Roughly after 700m you can go to his garage. His name is Sarath. I have many vehicles like, Alto, Viva Elite, Nissan K11,K12, Prius and he is expert on almost all the brands of vehicles. Harry (aq) also commented on the same person.
