if i was in this line, i wouldn't say that abt myself. so no, i'm not a dealer.
going by the current dateline, i think u'll need a dealer to do it for u... otherwise these are the norms...
1) insurance - your current underwriter would have sent u a renewal notice. u might have missed it, else u can call them to do a renewal for u... they can also renew your roadtax for u. so it's 1-stop.
2) u should carry on your instalment. and ask dealer to full settle based on paying the last payment on 3/mar.
3) can only transfer car when there is no outstanding loans on the car.
4) Nominal fee is subjective... if the dealer buys from u cheap, then there's no further fee. if u use a broker, there is a fee. if u sell yourself then u incur no fee but u prob dun know what to do.
5) selling yourself - u can only get higher if your buyer is dumb. otherwise it's well known that dealers sell cheaper than most direct owners... cos direct owners tend to be emotional and die die need to get a certain price to settle their loans. most times, direct owners still end up selling to dealers at crap prices... SO, sell our car below the existing market price, and dun try to do better... Unless u have financial power to hold. otherwise u lose more - i guarantee.
do think hard before u embark on this. learn to take your time if needed, and dun suddenly try to solve everything now by 3/mar simply becos u wanna avoid paying more... becos u dun actually pay more... it is perceived.
most sporeans lose a huge chunk of money when buying and selling cars...
