is it a good upgrade from viva 850 2010 to 2nd hand saga fl manual 2011 @ rm23k ?

hi all...i need your all comment very badly....

currently i'm driving viva 850 manual , i very satisfy with the car FC (roughly 0.10~0.13 cent per km , rm2.10/litre) and performance (can go genting uphill with 5 adults) (no modify , all is stock condition)...

but due of my job needed to put in foldable type ladder + working accessories....i always put the ladder & accessories on rear seat....but day by day , i cannot tahan ald....everytime want go fetch ppl , i need to return bk to hse and remove the ladder + accessories out frm car = ="
and my house at first floor , very incovenience !!

my viva currently still hv roughly 21k outstanding , RM350 x 61 months...luckily 1 of my frz he attend to sambung bayar my car and give me rm1k as token of sincere

i did some research & i have 3 options now

1 = used SAGA FL 2011 , executive spec + 15" sport rim RM24k OTR
2 = new SAGA FLX SV Manual , RM33,888 OTR
3 = new SAGA FLX SV Auto , RM36,888 OTR

is it true that new saga flx sv FC is much much better than previous version such as saga blm & saga FL ?....

if compare wif Saga FL manual & saga FLX SV manual , the FC just only minor different or huge different ?

roughly how many km/l or 100km/l for saga FLX (manual) & saga FL (manual) ?....

additionally , if i choose the new saga SV ....is it tat i'm stupid to buy manual ? most of the ppl hate manual due to city always jam and troublesome , but i'm loving wif manual as the manual is fun to play and less FC.....
& the SA told me , he recommend to buy auto instead of manual ...bcos of the new CVT gearbox & resale value , is it true ?

which would you choose ?...
used saga fl 2011 wif full spec + sport rim ?
or
new saga sv ?

i placed FC as my main concern , follow by handling and accessories

thanks

Anyone could share the FC for

Saga flx sv cvt auto
Saga flx sv manual
Saga fl manual ?....
