i know a few people around but they are either Nissan experts or Kia experts. Corolla was never with me as a personal car.
A good friend is working in Toyota Kabul if u want to get your car checked over there
Seriously he used to have a workshop in I-9 for like an year and it was party time for me at least. i just used to hang out around to get some knowledge. He was qualified from Toyota japan in some areas and his charges were very nominal. After he has left for Afghanistan even i have to resort to Dealership for routine maintenance.
