The old cultus was the real deal. I had the 3rd cultus in Karachi when it was launched in 1999. It was excellent compared to the later versions. Later models of Cultus from 2004 onward deteriorated in quality. When the efi variant came out , Suzuki really dropped the quality of the body , interior and escalated the prices.
It maybe 12 years old however it is far better then the current ones in terms of build quality. So the age part makes no sense. Fair market price will apply.
7 is rather high even for the best of the best cultus. Rethink what you should sell it for.... Im sure it will sell easily. The engine bay is excellent.
