People aren't being rude or hurtful, just realistic. Which I think you need to be realistic too. You either need to adjust your budget or compromise on age / milage / spec to pick up the A4 you want. Milage isn't an issue as Bez said above, my B7 has done 129k and still as good as new, its more down to the servicing and the previous owners driving style, oh and a fair slice of luck. If you can't afford the car you want, either keep saving or chose a different car. Mondeo / Vectra are a similar size and your more likely to find one of those within you budget.
