I sense so much suspicion in yr thoughts. thats no way to live. One needs to do so many things, if you keep on thinking others will ripe you of, you cant do anything in life and probably live on in worry.
I bought toyota certified scion what you call celica in Pakistan, , it never had any problems, it was little bit more expensive, yes it was trouble free toyota certified car, any issue i was not to worry, i could send to toyota, get free lunch coffee/ride i had access to services... i had other things to worry about, not a car
certified cars are to make life easy.
here in Pk couple of years back i bought starlet, more expensive than i thought should be market price but seller was a subborn person, in shahdaman whatever that area is called, i needed a car, used it, now i put it forsale, big deal. it ran fine, cheap 300k car. but its there better than nothing, no certified but still it worked for me, went to pindi on it too.
dont put so much pressure on yr head,, a lot of guys do that on forum .
you can easily buy parts for yr corollas etc , everything is there..
i should be more worried, i keep a very very rare car " ae86" in Pk.
but common..relax on forums, yr thoughts will come out more comforting to others.
