2001 Mercedes Vito 112cdi- SPARES OR REPAIR in Bournemouth, Dorset for sale

I have owned this van for the last 4 years, having bought it from my old boss (it was our work van) who had bought it new, so I new the history of it. Its done 238.000 miles and would still be going and not for sale if it hadnt been for the recent issue !! Basically a couple of the injectors have been stuck on for a couple of years and I was advised that it may be more of a job to try and fix them that it would be to just leave them as the engine was operating fine - unfortunately this has led to a huge build up of fuel/carbon mixture over the top of the engine (shown in pictures) and has completely buried the injectors and all associated wiring etc etc and is now such a labour intensive job to fix that I cant justify paying to have it done. This may well suit someone who has the time and knowhow to fix this, as the engine is still ok (as far as I know, but this is not guaranteed). The garage guy I deal with thinks its probably just an injector pipe or a wire that has broken in amongst the thick black mess, but to find it will be hours of work and it all needs cleaning off and probably new injectors etc. The van is fairly used and a bit tatty, the doors have rust at the bottom etc which is partly why I covered the whole thing in vinyl (the vinyl job is much more tatty than the pictures make it look, I did it cheaply and in a rush ... it looks good from 5-10 feet away, but messy up close) ....... it has 3 good tyres and various parts replaced over last year or two (Alternator, Auxillary belt/tensioner, front discs and pads, water pump, high pressure fuelpump) - so if you dont want to fix the van, there is plenty of stuff on it that can be salvaged as like I said, it was still running just fine before recent breakdown. I have fitted out the back as a basic camper/bed as this is what we used it for, but I have removed all speakers/stereo etc which I intend to use in a new van. Please contact me for any further details, the van is not driveable so will need to be towed away - I have it parked up at work as this is also near to where my garage is and I dont want it on my driveway in the way :-) .... so please contact me for viewing as will have to meet you there. I have all paperwork etc etc and service history since ive had it - all is genuine and im only selling it due to the issues ive just mentioned. I live in Bournemouth and van is in Poole (Holton Heath) where I work.
