Winter pack includes the heated front screen and Fuel Burning Heater (FBH).
Rear PDC is standard on the SE as is heated Alcantara (faux suede) seats. It should have a 6 CD multi-changer stereo. If you are lucky, it might have the Harmon Kardon speakers, but most don't.
Why would they headlights suddenly go high and fail the MOT?
Not sure if it's just my luck or what, but a large percentage of the MOTs I've had done has flagged up the headlight aim. Fiesta, Brava, 306, two Defenders, two Freelanders - it always seems to come up. I don't ever fiddle with the headlights, other than to change a bulb.
In an unguarded moment in the pub, a mechanic suggested to me that if the aim is near some borderline he'll fail it, since it's easy to correct. Something to do with not passing too many vehicles straight through - looks suspicious. Sounds a bit cynical to me but it does chime with my experiences.
OP, you could knock the price down a bit on that one. Check:
1. Prop and bearings - do a figure-8 on tarmac. Not as good as OWUT, I know.
2. Tailgate window and handle - make sure it's not coming off.
3. Spend some time and check every function works - radio, dash lights, windows, demist, etc.
4. Tyres, front brakes, knocks over bumps or while steering, try to slip the clutch.
5. Check exhaust for corrosion.
6. Look for brake lines replaced with copper
7. Leaks on the undertray
8. Remove dipstick with engine running and check for blowby
9. Listen for a noisy fuel pump when key turned to II
10. Check all fluids in engine bay - a sign of care and know-how.
At 126,000 a well-maintained Td4 should be fine, but you are possibly heading towards clutch, fuel pump and VCU territory. If you can knock the price back to budget for these things, find a decent service history, and all checks out above, then you should have a nice vehicle there.
