It may not be the 'same warranty' but it's certainly not 'no warranty'.
Yes it may be a little more hassle to process - but you do have warranty coverage with DR - and certainly do have coverage from Kerso....
These bodies are considerably cheaper than standard UK sales - and there is a tiny addiional risk as a result..
However realistically - in all the bodies I've bought, I've never had to return one. Yes sometimes things go wrong, but statistically I'm prepared to take that chance for a £500 saving...
Kerso's stuff is generally UK repaired - as is DR... There are other sources you could buy from, where it's particularly more complicated.. but both of these sources have served the TP community well over recent years..
