Highly doubt it - they tell you to bring around a mechanic or someone knowledge able, but - way before my purchase, I was interested in a Defender 90 2.8i. Lowish mileage. I went and had a look in Montague Gardens, told the guy I was interested, but wanted to have someone have a look, they told me it wasn't necessary, and were quite pushy, but I insisted.
The next day I called them and said I could come through with the guy, sales guy said all good - when we got there, they "forgot" one of the sales guys had taken the vehicle to a potential buyer for a test drive. I was a bit frustrated, but - left it - a week later I tried again, again when we got there - the vehicle was suddenly unavailable as it had to be taken to have a minor issue looked at (apparently).
Not once did they apologies, even though I had fetched a 3rd party to take to them - left it at that.
