Hello everyone, I'm looking for some help and info please... I have my heart set a Audi A7 for my next car, playing with a budget of 20k. Need help with the model and spec I should be aiming for? Also, what extra would be advantageous for me and the car? Sorry.. Also what kinda mileage should be my max? Sorry for the bombardment of question.. it's only this will be my 1st Audi and the 1st time I'll be paying over 3k for car . Any advise would be helpful Thanks guys
