Thanks for the help, I've been informed that the only known problems are a suspect wheel bearing and an occasional squeeky / squealing belt. I'm test driving the car on Friday, but as long as that's all that is wrong I'm fairly sure it'll be a sale.
Assuming the wheel bearing is goosed, anyone know what the cost of these are (both front and rear as I'm not sure which one is suspect yet) and also I guess squealing belt is usually down to tensioner or excessive belt wear, again if anyone has a cost for these that would also be great.
Ok here's the update.
Took the car out today, and to be honest she's tatty and has obviously lead a neglected life (reflected in the price) most of it's cosmetic, but there's 2 things that concern me one more than the otther.
There's quite a lot of noise coming from the rear end, I suspect a dodgy wheel bearing (or bearings)....relatively cheap to put right however, should it not be the bearings does the RX suffer from suspensions problems like the old LS used to ?? and if so am I looking at a high bill ?
But more importantly and the thing that is really concerning me is the fact that the expansion resovoir had almost no coolant in it, and with no obvious signs of external leaks this can only mean she's loosing water up the exhaust, does the Lexus suffer from head gasket problems ? or is it usual to loose coolant over a period of time for no real reason ?
Thanks in advance
