There are actually a few ECR trucks in the DMV area, but I can't recall who owns them. Here's an interesting
post by the owner of ECR, cautioning people to be careful of trucks advertised as "built by ECR".
In the US Land Rover community, especially Defenders, their reputation is sterling. They are the standard by which other restos are judged. BTW, ISTR they only do NAS Defenders now, which is a really narrow market. However, with the flood of ROW trucks coming in, we may see some ECR ROW builds.
Years ago, they did Range Rover Classic projects as well, so my long term plan had been to ship my rig up to ECR for a frame off full resto. When I found out they stopped taking Range Rover projects, I was bummed beyond belief. If I didn't want to build my own Defender, ECR is definitely one of the shops I'd use, i.e., budget no issue.
There's another shop called East Coast Defender, they're based in FL and are relatively new. Their website is slick, compared to ECRs, but I can't really comment on their builds as I'm not familiar, but I suspect they chose their name for a reason...
In addition to asking around at Defendersource.com, I'd also contact ECR directly. They're also pretty responsive to their Facebook
page.
