Thinking of selling my 1380 as i'm just not using it (around 500 miles a year).  What do you think its worth?


In 2017 received a fresh coat of Black paint with Old English White roof after some welding work, including: cross braces to properly support side mounted Sparco bucket seats; plating beneath the roll cage feet; welding up the screw holes which previously fixed wheel arch extensions, new wings to suit the 4.5x10 Minilites as the old ones had been cut to accommodate wider wheels.  There was also an earlier light restoration approx. 15 years before when sills, front and rear valences, door skins etc etc were replaced.  A very solid and rot free shell.  Always garaged.


Engine is a Slark 1380, 296 cam, Weber DCOE45, straight cut box, 3.7fd, big valve head, ultralight flywheel, wedged crank and 1.5 high lift roller rockers.  Lumpy at tickover and  doesn’t get going until 3000rpm , but when it goes, it goes!  Fully adjustable suspension, AVO dampers etc, 4 pot calipers, 7.5" discs, so cornering and stopping to match.   Roll cage, harnesses therefore only 2 seats.  Very quick, very noisy, not for the feint hearted but great fun.


MOT til October.  Based in Dorset.

Hi - Mini looks awesome and very similar to mine, other than roof and body are painted the opposite way round, but 1380 and similar spec. I was browsing here to try and value mine, I've been told circa £12-£14K, what are your thoughts ? Cheers
