Purchased a 2009 Honda JAZZ VTIS Crystal Black

Hey guys,

After being a very happy owner of a 2005 GD VTIS, i went and purchased a Honda Jazz GE 2009 VTIS 5 speed man in crystal black color.
The car is in immaculate condition purchased it of a one owner 65 yr old man and it has only 30,000kms on the clock, It was the old mans pride and joy not even a single dent and apparently he never drove the car offroad / gravel as he was scared of scratching it , i found that hilarious !!!

Planning to do a few smart mods and don't want to ruin the vehicle.

Just wondering what would be the first few things to do that will not cost much and will improve the Jazz's performance / handling.

was thinking of changing the springs to Mugan lowering springs? are they any good? and how does your jazz handle with stock shocks with lowered springs?

heres a pic of the black betty
