I have lived in Pakistan for most part of my life and even had an auto servicing business, and a car or any production item does not entail one questioning what a country can do or has capability of.. Iran has nuclear facilities but they dont have hybrid cars or fully electric cars. That does not mean they cannot afford it, it does not make economical sense to them.
My reasoning for the third world country like Pakistan was because of its rules, regulations, duties and costs in general ownership of cars. You can get yourself a Tesla roadster (electric sports car) - I dont care, will it work YES, will it be economical, (TBD) and can it be put back into service once failed, Ask yourself this question...
A product is only good till you have its support, because you yourself did not design it, and when you are stuck with something that you cannot cannibalise parts from other similar models you are for sure STUCK. a very simple example is the newer MB vehicles with smart keys, why do you think you need to buy a NEW KEY and not just reprogram another used key, it does not have a physical key blade and all of those type keys look exactly alike. It does not work. So you go about to "import" a key and you need to dish out money.
coming back to the point, people in Pakistan have to cherish their cars because its a high value asset that does not depreciate, this was not a problem when cars were designed with a 25 yr EOL with basic dead nuts simplicity like the datsun 120Y. But when you have a complicated item with no support it becomes a nightmare, just like most offices in Pakistan do not use checkpoint as a firewall while in other countries its standard.
So you might have all the scientists and engineers who can make a kicking nuclear reactor but they are useless for this purpose of discussion.
Further explaining - a car made today with a medium budget has an estimated EOL of about 5 years after which it is expected to be recycled into a new car, keep that in mind, I doubt you will buy a 9 yr old used airconditioner for your home (estimated EOL being 10 years for such appliances). It would be needing extreme service investment and you still wont be at 100% unless its a product that is made like that (such products have double pricing usually). All this is besides the very odd problems that Pakistan has in driving, floods that look like a river and a general breakdown maintenance mentality in upkeep of vehicles.
So wait for the scales to settle then put up something.
great example is the brand of Nissan, Fiat, Daewoo (GM), why do you think they are considered headaches???? expensive spares and unreliable support from the distributor, I once went to Nissan to buy a new torque convertor and some transmission solenoids for a car they officially sold - Nothing, they did not have the parts and neither offered to get them, I had to source then myself from Thailand. If the distributor carrying the brand name does not care then the item is as good as scrap metal when its out of commission.
btw - the HKS thread, if you or anyone in their sane mind can prove its worthiness by explaining the basic physics of it and that it can increase 14hp by it, I will personally consider them ALLAH, to hell with the concept of shirk or anything.
