@pauloti;
The difference between Baricho and Kirinyaga is that the former predominantly has used parts dealers while the latter has predominantly new parts dealers.
If you want to reduce the chances of buying a stolen part,then you should make sure that you buy a new part.
'NEW' does not mean that it is genuine!! It could be from Taiwan,but it is still new...has never been fixed in a car.
The used parts will always be genuine...i.e.,they were manufactured by the car maker,or the company that makes parts for the car maker....
All stolen parts end up in one used parts shop or another.
If you want truly genuine...go to Toyota EA...and carry enough money
Behind the gardens...Behind the wall...Under the tree (Including: Red...Dark Blue...Yellow)
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
