Just to update this, I rang the dealer, who seems to know little about the car and seemed offended that I should even consider asking key questions about his stock... Sadly seems like one to avoid.
That ADG car does look like a good one, shame it misses the March '06 road tax date and therefore...
I'll have a look, thanks for the feedback. What issues might lead someone to do a Terraclean? I've always considered it snake oil, unless trying to save a DPF, which cleay isn't the issue here!
HL03 GTZ, a graphite coloured 4200 coupe CC with a trader in Nottinghamshire.
He says it has recently had a Terraclean - which worries me that it was done as a cheap "fix" for an underlying problem.
Any of you folk know of it?
We drive to Rome a couple of times the year with three kids in the car. I love the drive, which we do basically non-stop from the Midlands. Door to door usually works out at 24 hours. If you or your partner don't like driving though, take the plane!
