INH is just okay at best, visited them with my mercedes two times, seriously not impressed, some of their practices are appalling, oh and dont worry Dr. Zac if you met Mr. Naeem he assures everyone that he can order parts from dubai, they are poor at even doing mercedes cars and haven't got a clue with japanese models. our close family freind who despite us warning them still gets the car done form them believing in their kind words is still waiting since a month for his rav 4 transmission control module to arrive from dubai as ordered by INH, its been a month and no part has arrived and car is immobile. i wouldn't even mention the stuff they did to his mercedes, first failed airmatic and now failed ABC and they are using shotgun technique to diagnose it.
that said for basic maintenance work its good enough and i have seen them working on vezel before, infact the first time i saw and sat in a vezel was at INH, just be careful and exercise your own judgement rather then blindly relying on imported parts form dubai story.
do a pakwheels search , you'll find more horror stories about INH like the one by nousher 101 however if you yourself have the knowledge then its a good place to start and just supervise over them that they follow correct procedure.
