Purchase and history of my 1970 Citroën ID20/ Dsuper5 convertible

The 1970 Citroën ID20/Dsuper5 was bought by me as a Berline, 09-11-2007.

Later I discovered that it is an ID20 according to the registration papers, but that an original DX2 engine is mounted with a 5-speed manual transmission.

That complies to the registration papers: ID20 with 2175 cc engine.

But according to all books about engine types and years, the ID20 with DX2 does not exist.  There is a Dsuper5 as a successor of the ID20 with DX2 engine, but only from 1972 on.

Well, I rather believe my license plate than the retrospective lists from all kinds of websites.  Because Citroën has done all sorts of things with different engine versions per country.

My ID20 originally came from France and was imported into the Netherlands in 1970.  The car was originally metallic green, but when I bought it it was black.  When I bought the car, it had doors with recessed latch.  I left it like that.  Unfortunately, I was never able to find a carte grise for the car, so I have to assume that the data in the RDW register was taken over correctly when the car was imported into the Netherlands.  I did check on the engine type and there is indeed a DX2 engine in it (2175 ccm) with 115 SAE HP.

After the purchase in 2007 I had a lot of work to get the car safe and reliable again.  Despite the still valid MOT.  The seller had told me that the reason for selling was that he could not get the car through the MOT anymore.

I kept the pictures of the original advertisement in 2007:

The car had been poorly or not maintained, all the sheet metal was bad, and the sheet metal under the car was also in bad shape.

The sunroof was leaking and the car was completely wet inside, also all the upholstery was soaking wet.  The trunk was also soaking wet.

After the sale was closed and the car was registered, I drove from Amstelveen to Woerden and the car drove unexpectedly well.  Both on LPG and on petrol. The car did pull to one side, but after pumping up all the tires along the way, that was completely solved.

After arriving in Woerden I parked the car in the garage.  My Traction Avant was ready and I had temporarily moved to another place so I had all the space to work on the ID20.

From the first discoveries I have kept some nice pictures.  The bodywork had apparently once been treated with putty, and over that the black paint had been applied.  The paint looked nice, but the putty came loose from the car everywhere.  When touching some of the protruding parts, the putty easily fell off.  And there was always rust underneath.  The previous painter apparently didn’t include the stripping or preservation of the underbody in the preparations -or at least didn’t do it adequately.

After removing the upholstery, sofas and seats, I first let them drain outside, and then let them dry out inside.

I immediately replaced the sunroof with a new waterproof electric Webasto folding roof.  That solved the biggest cause of the leakage.

Then I first worked on the bottom of the car and the trunk, because of the MOT.

After the bottom was done I replaced, repaired and/or adjusted the following things: Brakes, knuckles, steering, grease rubbers, leak bags, exhaust leak, hand brake, lighting, LHM, V-belts, engine oil, spark plugs, oil filter, half front train Right, tires and balancing, alignment, longerons reinforced, leak chutes side trunk, sheet metal all around stripped, preserved and put in black primer, gearbox oil.

After that the APK was passed and we took the car to France on vacation in the summer of 2008 and 2009!

In that period of 2008 and 2009 I drove the ID20 as a private car, but gradually it became clear that this car cannot survive outside.

Therefore I arranged for a second garage so that both the Traction Avant and the ID20 could always be parked inside and I purchased a 2nd hand more modern private car.

Then I was able to get back to work with the ID20 to refurbish the sheet metal once again.  I did a serious job of refurbishing it and cut out all the bad pieces of rust and sheet metal, bought replacement parts where possible and made new fender edges for the front fenders myself.

Because the whole car is made to measure at delivery it is very unwise to exchange parts of the bodywork like doors and mudguards.  With a hood or boot lid it should be possible, but it remains to be seen whether it fits between the existing fenders.  In the course of time Citroën has often had slightly different sizes of plate parts and because of the differences at all the factories you never know exactly what a second hand replacement part has as origin.  Let alone whether you can find out from your own car.  So I completely restored the whole original set of my car, and where necessary like with the door frames always processed only 1 door at a time, so that I could always fit it to the counter-frame.

The car was, after everything was completely finished, black.  After this I drove the car only a little.

In 2016 I came in contact via-via with a convertible builder in Friesland and after some back and forth I decided to have the Berline converted to a convertible in 2016.  The costs were quite high, but that included the retesting and license plate modification to Cabrio.  And the entire inside and outside of the bottom was immediately reinforced with 2mm plate.

During the conversion to convertible I also replaced the LPG tank, filling hose and supply line to the engine.  The LPG tank was also placed a bit lower in the trunk, so that there was enough space above the tank for the folded convertible roof.

A couple of years later, I decided to change the cabrio’s roof frame and alter the trunk lid to get a smoother rear of the car.

Then, in 2021, I decided to get the car repainted and in the process of doing this, get all the old parts upgraded like the fenders and so on.  This process is still ongoing (08-2022).
