high mileage diesel or petrol

Hi All

i have a budget of about 65k and i'm looking at getting an e46 individual m sport , i found some 320d, 318i, 320i, 325i and a few 330d. i just always liked the look fo the msport e46's and the individual wheels

I need some advice, is it worth it to buy te 320d or 330d with about 200 000 on the clock or would it be better to stick to petrol.

i know diesels are not great at high mileage but overseas forums are pretty confident about high km bms ?

let me know your thoughts, will i be buying a time bomb?

cheers!
