what would you Buy?

g'day everyone, im in the market for a 125 2stroke and ive narrowed it down to these three bikes(click on the link's to view ad's). this 01 Rm was has had little work done and after talking to the owner he can bring it down to 3500 and throw in some gear also. 01 Rm Link

this YZ looks like a good bike but it also looks like it has done a fair bit of work compared to the Rm... but its an 03 model. Yz link

same with this Kx ...Kx Link

thanks for your help

i didnt think i would waste my time with my personal details...I know i want a 125cc 2 stroke i just want to know which bike looks better and cleaner and which would perform better
thanks BulLy
