After initially buying the incorrect one second hand and finding the bits that would make it fit my van would cost almost as much as buying a new one and watching eBay for almost a year for a secondhand one i’ve bitten the bullet and bought one new.
Just Kampers had a deal on their eBay shop which meant I picked it up for £345.00 instead of £405.00, a considerable saving but still lumpy!
There are only a few options on the cycle rack front for Sprinters so the manufacturers can charge what they like, that being said the Fiamma ones are very well made, we had one on our T4 and was very pleased with it.
The rack arrived next day and there is a small amount of assembly before you try and get the rack attached to your van, instructions that come with it are very easy to follow. If you don’t want to scratch your rear door i would suggest two of you fit it, my door has a few bangs and marks on it so I wasn’t that worried and fitted it on my own.
Fiamma recommend you drill through your door and fit some anti theft bolts, I took the panelling off my rear door and forgot there was more panelling underneath!

You have to remove (if you have it) the lower grey panel as when you drill through that’s where the holes are!
All in all on my own the job took about 90 mins and now I can take either my bikes or electric scooters away without shoving them in the back of the van

I’ve left some bits off rack as where I live some people thing it’s OK to help themselves to your stuff, the joy of living in London!
