to be honest I went to germany to get my jazz as well, And Im about the same distance from Germany as you are , about ~1100km , for the 5k you CAN get the new Jazz in Germany which is miles better than the old one.
Looking to probably buy 2009+ jazz as well IF i can find a buyer for decent price for my 2003 one,
You must also realize when the time comes you won't really be able to sell your old shape jazz just because the new ones by then will get even cheaper,
If I were in your shoes and Had that kind of Budget for the car, 99% I wouldn't buy the old one even it has been superb reliable for me and economical- It's just getting old , and the engine is just weak and no fun at all!
