In reply to Philip:
This mainly applies to Little Black Cars like A3’s but extends to a disproportionate number of other Audi’s too. Firstly, ask for the quantum mechanical package; this ensures that the cars’ dimensions change with speed. The faster they go the smaller the gap in traffic they need to fit through – for relativity reasons, this effect can only be appreciated from inside the vehicle.
As it’s an Audi, ask them to upgrade it to a model with working indicators and a set of rear view / wing mirrors. If it’s a second hand car, the previous owner probably hasn’t realised that these are missing, unless applying make-up.
Get the steering checked as many of them have very worn steering judging by the way they unexpectedly drift from lane to lane.
Have the windscreen replaced with optical quality glass and not the usual one that renders red light invisible and distorts the drivers’ view so much that the car in front looks to be a safe distance in front but is actually only two feet away.
Sat-nav can be a useful addition, it’s easy to spot the cars without it as they remain stuck in outside lanes for mile-upon-mile and cannot find their way out of it.
Finally, ensure that the dash board is calibrated as many Audi speedo’s obviously underestimate the actual speed.
Did I miss anything?
A full tank of fuel and full sized or space saver wheel could reasonably be added to your requirements.
