Jazz is much more refined; more quiet, smoother CVT, better NVH. It loses in the power and handling aspect. Space wise it's actually very spacious, and the seats support well. I find the Suprima much more comfortable however as the Jazz has a tendency to sway especially on bumpy roads. It's worth it if you prioritise power and good handling over other things. You'll have to spend money on improving the NVH by doing sound deadening for the engine and road noise, but it'll be worth it.

Maintenance wise it is a lot more pricey to maintain compared to a Jazz as it has a Turbo engine. Basically you'll need to pay extra attention to the engine oil you're using as cheap ones can cause sludge to build up which will eventually cause the turbo to spoil. Not servicing on-time or early can also cause this to happen. Tyres are also much more expensive as it is 17 inches, but you do get a lot more high performance tyre options for this size.

The biggest headache that some owners will have is CVT gearbox failure. Quite many have had their gearbox fail in their Suprima/Preve, but some of them are very aggressive with the throttle. If you're the sort that can feather the throttle when moving from a standstill, you're less likely to have the gearbox fail. This applies to any other CVT gearbox basically, but Proton's current CVT gearbox is especially sensitive as it is using a clutch instead of a torque converter.

Overall I don't regret buying this car because I know what I want in the cars I buy, and how to fix most of the problems (especially rattling issues). Go on more test drives with the Suprima, and try to test for as long as possible especially in stop-n-go traffic situation. The CVT gearbox characteristic can be a really big turn off for some people, especially those who expect very strong initial acceleration (I hate this kind of drivers cause as a passenger they'll make you vomit).

Points	Jazz	Suprima
Power	-	Faster. May be slightly slower at a standstill for a short while due to CVT initial engagement characteristics, but it'll push beyond 140KM/H easily especially after a remap (MBO by EA Autoworks). It basically is like a 2.4L NA Engine but with a much more consistent acceleration power at low speeds due to the CVT + Turbo combination. It'll max out around 200 to 220KM/H, whilst a 2.4L NA should bring you slightly higher than that w/o being super stressed out
Handling	Soft;floaty. I don't dare to push my sister's E Spec Jazz pass 80KMH, whilst I can go up to 130KMH in my Suprima S at the same corner	Stable; Really gives you a lot of confidence
NVH	Much better	Fairly noisy engine/gearbox. You're recommended to go for proper engine/gearbox noise sound deadening. Get it done at proper shops, not the ah beng ones
Space	About the same	-
Reliability	Generally more reliable	Depends on your luck/driving style. Some people don't have any major problems with their car, some do.
Fuel Consumption	Very economical (20KM/L can be easily achieved on a highway with me driving.. My sister can only get around 15KM/L	Very poor for city driving, good for highway driving (6L to 8L/100KM).

No idea , maybe because i drive a old saga BLM .. maybe they think i cannot afford ..
seriously feel so sad lol ..
