I bought my 406 HDi Estate with 168,027 miles on the clock.
It had:
* No record of any cambelt changes. I've no idea when it was last done.
* No record of an oil change. The last owner did 10k in it, and told me he hadn't as much as lifted the bonnet.
I've now done a further 3,000 miles in her, it's like driving a time bomb

I also have:
* excessive play in front NS wishbone. You can rock the wheel right back with the car on the ground!
* Front brakes made a horrid metallic noise coming back from Di's last night. Sadly, the meat on the pads has gone to better places. It needs handbrake shoes, and at the same time, may as well do rear disks and pads, and then a brake fluid flush.
There is some play in a rear wheel, which I need to address.
Also a blowing rear exhaust, and perished handbrake cables.
I am afraid, Easter weekend, I am going to have to sort out my own car - else before long, I won't be able to travel anywhere at all

On the plus side, I put some Texaco diesel in last night - their premuim stuff - and the hesitation / injector clatter has very significantly reduced... Odd !
