I am considering buying a cheap (£2990) old renault (51 reg 100 000 miles) laguna privilege 1.8 petrol. I have heard some very negative feedback about its reliability and faults. However, I was thinking that having done 100 000 miles this laguna must either be ok or it has an extremely patient owner (i.e if it is highly unreliable). BTW, is this price ok or should I be asking for less?
