Hello, The previous owner may have done high mileage and had one or two missed services but the fact is that’s nothing for a Lexus engine to have done 107,000 Miles. It’ll do 300,000 with no bother, so as long as no problems are present , I would ask them to check the hybrid system and provided no issues come up I’d buy it. Seems like you have a good deal and to quibble over the odd £250 seems like a waste of energy for such a car. Sent from my iPad using Tapatalk
