Thank you for the reply, and I think that almost decides it for me.
I’d wanted this car once he came to sell it for a while now, but this job sounds like it could end up being a right pain, and I don’t seem to be able to find anyone near me (Manchester) that I could rely on or, more importantly, that specializes on Lexus, aside from a dealer.
It needs two back tyres and the batteries have gone on the tyre pressure sensors too, so having to spend up to a couple of thousand right before Christmas isn’t ideal. It’s a shame, as the car is lovely otherwise, and it’s possibly even worth spending that sort of money, next to what it’d be worth once the work is carried out.
Anyway, thanks again for the information.
