How to get a new Motorbike without loosing much money?

I got my bike 2 1/2 years back....it was 2.8k....now if I go n ask from a shop, they say they take in for just $1k plus... thinking of getting a nother 2nd hand one without oosing a big margin. the COE is expiring in less than 2years time...which costs about 1.5k to renew. should i repaint the bike b4 sell off (got some scratches). If i buy a bigger bike it'll be more comfortable but my expenses will increase... thinking of getting a bike wic costs arnd 3k...should i sell it n buy a new one or keep it but renew COE?
