My advice,
don'k book Proton's car after launching
IF u want it fast, better book before launching
Proton's has been doing this for years
promis promise & promise
just imagine last month i heard my friend still didn't get his Persona after 6 month
to make it worst, he changed 2 dealers already

for NEW SAGA, it is advisable to wait at least the 3rd,4th or 5th batch get their car
1st & 2nd batch is people who order before launching
3rd, 4th & 5th batch is people who book after launching & willing to wait 6 to 9 months, even worst than that, may be 1 year
It's better & easier to wait after a year or more

BUT if u want to take the risk, be my guess
I learned a lot how proton's work
they didn't produce stock for the market
they like to wait for market 1st, how many people ordered etc etc
from there, they will produce stock & most of them in low QC
lot of probs

IF u want Proton's car with less prob, wait a year OR more
read lot of news about new SAGA, their owner, probs so on & so forth
read lot of review about SAGA before jumping into buying it (but sometimes Proton paid writers to write false statement about their car)
listen what their new owner want to say about their car after a year
join cars forum like MOTORTRADER & AUTOWORLD to keep track on SAGA performance & probs

For the time being, while waiting, keep your money, top up your downpayment
don't make loan repayment more than 7 years coz Proton's car can't survive 7 years
Proton's old car like Wira & previous model can stay that long BUT not for models after that
my brother in law WAJA Campro, got major probs last year, 7 years like my car, but major repair
top up your downpayment & loan repayment below 7 years
