If you have the time to spend on updating this, the 1970s Citroen DS 21 Super 5 here could be a really special thing.
According to the seller, the car dates from 1972 and 'is in not that bad condition considering the year'. The car was Irish registered, belonging to a doctor, before it was brought to the UK by the current owner, who is selling it now.
The car, with 83,000 on the clock, 'runs and drives well' and is original, but it does have 'some surface corrosion' on the panel work, but 'nothing major' which would stop you driving it. It runs fine, but does not have an MOT, so you do need to consider that in regard to collection.
But it does look like a cent option to take to the next level if you have the time. With the price at £1,550, it is priced well for that too. More images on the listing.
