Audi 100 44 Purchase advice low mileage

Ladies and gentlemen, I have been playing an Audi 100 Type 44 for a long time. Unfortunately, many are arrested or the same. Now I have received an offer for a BJ 1986/90 hp gasoline, mileage detectable around 10,000. without damage, rust etc. tyres due. Tooth-straps already renewed. Service always at VAG. Last service was in the 90s. WILL BE IMPORTED ALSO: Service + tires How much can you spend on the car? Must the car me transport your 100km on your own axle, do I have to worry about the old liquids or something like that? Vehicle currently has TÜV. I hope for your help. Thank you in advance!
