I have my Series 1.5 Competizione on auction on Bring a Trailer (BaT). Car is fully described and the videos are beautiful (as is the car itself!). Bids from UK also welcome! Car is UK registered with MOT to December.
https://bringatrailer.com/listing/1970-lancia-fulvia-sport-zagato/Can recommend BaT as a method of publicising (and selling) if you have an unusual car and the right approach. It attracts more bidders from Europe than you would think
