OK, first post in ages but I'll chime in to this.
I got mine from them last September and was very sceptical because of their previous 'reputation', especially with the Evo world. I checked with a few people from here who had also got theirs from SVA that year and since they didn't seem to have any issues I went for it, being local helped their case I guess.
The car came in, as described, complete with some 'added bonuses' that weren't mentioned like the parcel shelf, factory rear tints and a Kakimoto catback. The original registration process was as you'd expect really, MOT's, DVLA, you know the score. Whilst this process was going on they snapped a wheel stud and 'forgot' to fix it until I mentioned it. Thankfully they did indeed fix it, at their cost. Also had a dead battery when I went to pick the car up from them, they did replace this on the day, again at their cost.
All was fine for 6 months, the tax they provided with the car was due for renewal. Fair enough, off to the DVLA website I go, fill in the details from the reminder and get greeted with a "No MOT found". Awesome. I didn't even bother trying to speak to them about this so not sure what would have been said.
In response to Liam's comment from September this year; as far as I am aware, the owners now are the same that have always owned it.
I'd also love to know who had my old CTR from them after the owners daughter had been driving it around for a while, whoever got it had a potentially cracking deal on the parts I left on it! xthumbup
