premium window tinted is quite good..

UV protection confirm yes. Coz i got wearing HOYA spectacles. stay inside cabin, my specs wont become black. Heat rejection i consider average.. under very bright sun, still can feel the heat..

fuel consumption is differ by each other. mine is 7l/100km for working routes.. if 1 whole mix driving, 8l/100km.. it's depend on distance,area,traffic condition, driver attitude.. hardly to make comparison.. just pump the petrol once finished.. just that easy.. LOL.. no need go border and thinking on it everyday how much u use everyday.. coz should consider it before purchase the car..
if u get premium version of Preve, actually no need go for tinted anymore.. price difference around 10k between executive and premium is the auto fold side mirror, auto rain sensor, auto headlamp, auto climate airconditioner, paddle shift, turbo engine, lousy GPS headunit (but radio, bluetooth well done) and tinted.. the price of window tinted is quite pricey if go to dealer.. so consider it ba..

CVT actually no gear one.. just computerised make it sounds like 7 speed.. but turbo engine is not running fast.. but to get maximum torque 205nm to pull heavy Preve.. if read the specs, preve is heavier than civic, altis..

without turbo, 1.6l engine is quite difficult to push.. that's why got people complaints for powerless in preve executive.. because they have no knowledge..

but 1.6l with soft turbo, it's enhance the weakness in executive.. the turbo of preve is not for racing, but to enhance fuel consumption and better power to push nearly 1400kg of body weight..

fuel consumption people said very bad.. if compare with my aunty new civic.. both are more or less same figure only.. not significant different..

good luck for you.. if successful be a preve owner, be ready to face the typical questions from others.. but still wish to enjoy the car.. at least im enjoying my preve premium.. lucky owner here, no issue..

Yes, all of them

Yes, basically the HU is rubbish. Haha
So you may change to aftermarket one. Do some soundproofing, upgrade better speaker, your car is almost perfect.
BTW, seat quality is also Preve problem. wrap a leather one is an option.
