When my son wanted the Z3 we looked at various options and set out on a Saturday morning to look at 4 cars. First stop was a semi retired dealer [had 10/12 cars for sale, spent all his life in the trade] he had arranged to bring Z3 to his house in countryside outside Knutsford for us. He works by appointment only. When we had phoned he pointed out 2 faults he was waiting for bits from BMW dealer. We looked at the car, it seemed rather nice. Took my son out for 15 minutes then came back ,suggested my son and I went off for an hour ,at least,see what we thought.
Came back , absolutely no pressure, he was not interesting in moving from the price [in the end he taxed it for 12 month] it was genuine and we still have it Car seemed genuine, so my son bought it, just a pity all motor sales are not the same.
