I want advice regarding whether to buy 2.0D or Gli with CNG (I ve to buy brand new in both cases). Is Gli on CNG powerful enough to drive comfortably in local crowded traffic with AC on? What is the effect of CNG on engine life? Please some one advice me regarding resale of both these cars. Its a difficult decision because couple of years ago i had civic Exi on CNG, but there were problems of frequent tuning, power drop with Ac and no trunk space.
Using the original intended fuel will always be better.
Diesel has awesome drivability in traffic due to mega low end torque.
I suggest buying the diesel.
With any car there is going to be a power drop with the AC on thats just normal. But if you want less hassle and stuff go for the diesel.
