WTB car topper dinghy

 Looking for a cheap car top tinny if any one has one not getting used . Had one in the past so 10 to 11 footer (3mtr plus) would be perfect to fit on my roof rack . I have a 6hp outboard to go on one so only need hul. 

Looking to get one licenced but as long as it has a HIN number i could get it licenced myself .

Will only be used on the odd caravaning trip so trying to keep cost as low as possible .

If you have or know of anything available please let me know .
