Alto AGS does have excellent resale instead. To top it off, Pak Suzuki has always kept its quota limited, which has also enabled it to maintain its resale value.
I own an Alto AGS as well, only 1,400+ KMs driven so far. The only issue which bothers me a lot is that at lower speeds with AC ON, the car jerks abnormally, like the AGS seems unsure whether to stick with 2nd or 3rd gear.
The plausible solutions are: 1. Switch to Manual mode and change gears yourself or 2. Turn off the AC while driving at low speeds.
Never experienced this thing while driving cars with conventional auto transmission.
Other than that, AGS is a pleasure to drive especially at speeds over 40 Kmph.
