awrite...so lets answer u one by one
parts...there is no problem whatsoever of spare parts of the car. it has all the same parts as that of a vitz. example, i needed to change the rear wheel ABS bearings as they were giving some noise. i was pretty worried that it wud be a tuf deal . believe me, i went to pindi kabaree, and found hundreds of them, and changed the whole set for just 4000 rupees, and they are working perfectly well 
2...dificult to sell....i dont agree with u sir. i posted an ad few days back and there were more than 20 calls per day on the average on ma cell fone with very decent offers. ma brother meanwhile test drove the new gli. he is a surgeon in bahwalnagar, and he immediately gave a me a ring to drop the idea of goin for new gli
3...CNG performance..i partially agree with u. but, its only valid for the automatic transmission versions in platz. in manual ones, u have a wonderful feel of the car and there is no problem as such. i have travelled from islamabad to quetta twice on it already, and m goin again on 19th this month inshallah. and if u talk abt economy, then hats down to platz in comparison to city
trust me. there is no comparison there. i have a 60 kg cylinder, and with full pressure on GT road, it gives me a regular average of 260-270. unbelievable? but trust me its true. last time in march, it gave me exactly 235 kilometers on motorway while goin to faisalabad. here in quetta, i just filled ma tank today, and in local drive inside the cantt, it has given me an average of 173 kilometers in last cylinder
stil, we all have different choices
and yeah..one more thing which @storm bhai said...resale doesnt save ur life in accidents
hope i get the point across
