Dirt Bikes Northern Ireland

Where could i buy a perfectly working scrambler dirt bike?

For £100 (about $160) or less, with no strings attatched.
I tried Ebay, but its useless

Pleeeease! where can i buy one
(I hate using credit cards so i’d prefer if you reccomended someone i could phone or see personally)
(I live in Northern Ireland)

The only way to get a deal like this is from a sympathetic friend or family member.
