They were slow puncture.... so it was only after not driving the cars for a few days that i noticed. No, definitely not aware of anything untoward with the car - just the usual spiel that car is in great condition etc..... I sent so many emails - almost pleading for just a reasonable response - it was so stressful. The only way they agreed - was when I took it to BMW Inchcape to prove it - left the car there for a few days and they saw that 2 tyres had gone flat.... the BMW inchcape person then contacted this "senior" guy - and then they agreed to replace tyres...... but still had not acknowledged other issues.
Roy , thank you - I will contact you. I also thought the same re Lexus not wanting an unhappy customer...but this "senior" person just stopped responding...by which time i was just fed up..and had run out of energy after fighting this for about 6-8 weeks. i did log all of this on something called Resolver...but that did not seem to amount to anything.
Anyway, thanks again, all.
