After a pretty decent coffee from their machine I then enquired if I could have the use of their B8 RS4 demo for the day, and after a quick licence check the keys were handed over to me without hesitation

No work for me today, so I went for a pre and post-lunch drive totalling over 100 miles of Kent's best A and B roads. At 17 mpg (I thought I was trying, but I think it's probably more economical than the B7) all it cost me was £40 in fuel

Lovely car; needs a bit more noise as standard, I like the throttle blips on down-shifts and the speed of the gear changes with the paddles makes it even more of an overtaking weapon than our cars I think. It perhaps looks a bit too subtle for an RS, but having said that it did seem to attract a fair bit of attention - maybe the colour helped with that.
Here it is:


Anyway, went to pick my car up. They have a tech there who specialises in the RS models and I was assured he had given it a very thorough check over. It's currently on 69,000 miles. No issues found with the arms or bushes, but an advisory on a very minor weep from the front near-side damper. Think I will speak to Unit 20 about this re. a repair for this as the other three were fine (all four were replaced under warranty in 2009). Might also speak to Audi UK to see if they will consider any goodwill in the circumstances.
The oil cooler pipes were just starting to corrode but not too bad, so they just coated the joints with something to help prevent it getting any worse.
Coolant was low and I agreed to a pressure test and top up. No problems found from the pressure test thankfully, so peace of mind there. Did get an advisory on rear disks and pads, which is probably fair enough as I don't think the disks have ever been done. Was quoted £900 for this, so I think I'll get a couple of indie quotes first!
Total cost inc. the pressure test and coolant top up was £180, and the oil cost me £80 ish, so pretty happy with that. All in all a very good experience, and the B8 for the day was a bonus!

p.s. have posted a few more pics of the B8 in their picture thread
