brake and steering wheel judder on test drive

Went to a car supermarket in London, and test drove a Jan 2002 S80 2.4 SE. 80k miles, 6 services at Volvo. Owned by lease company.

Next service due in 3,000 miles or April 2006.

Anyway, car is very clean, inside and out. So I drive it round the block a few times, did an emergency stop, and it was fine. Changed through the gears smoothly too.

A couple of points though:
The back box was sounding like it was blowing (not bad though)
The steering was pulling to the left
Feeling of juddering felt through brake pedal(almost like ABS kicking in) at low speeds, but not felt when doing emergency stop
Steering wheel vibration felt when turning the wheel slowly, and vibration felt through the brake pedal too

However, once car was 10mph or more, then it drove fine.

They promised they would fix everything before I come to collect it, so I put down a 200 pound deposit. I collect the car Sunday, and will test drive it again. If the problems are still there, I can get my deposit back.

I figured the issues are likely to be pads/discs/low ps fluid/balancing/tyre pressures, which are perhaps quick to fix.

Any advice?

im sure they most likely are minor defects however i would check very carefully that the car pulling to one side is not due to accident damage

cheers. forgot to say am getting the car for 6.5k
