Yep, everything @alcapone mentioned is correct! CNG on a Margalla is fantastic and its performance/consumption is definately superior than to a Civic 95.
But if you run them on petrol, Civic is uncomparable as far as Im concerned!
Spares are and will always be cheaper for Suzukis. Naturally,they are being made in the highest demand comparitively and they are the worst quality in the market; low quality=low price generlaly.
