Renault Twingo C06 BJ. Dec. 99 Model 2000, checkbook ? Maintenance ? When ?

THEMA : Twingo, when do I have to do a big and when a small maintenance, at how much KM respectively years ? Hello together, I am new here and have been looking here in the forum already, but not yet read the correct answer to my question. Even though I have a Twingo BJ 99 model 2000 and am second owner. Since the previous owner unfortunately did not have a checkbook and also had no further invoice about repeats I would like to at least regularly keep my Twingo waiting n. I bought the Twingo a year ago and since then absolutely nothing has been done at all. KM stand on the date of purchase was around 70,000km KM stand today around 92,000km Since this year nothing, really nothing was done, except on liquids water and windscreen wiper stuff made by me. On 17.02.09 the left drive shaft had to be changed (exchange shaft, no NEW), this I had done at Renault, then KM stand 81,000km. Yesterday I left after consultation with Rena ult make a complete large maintenance + timing belts + water pump. For almost 700,- € an expensive matter. Now I would have known from you, how much KM or years I should do the next small maintenance, or again a big one. I unfortunately did not have a checkbook as already mentioned, but from renault let me issue a maintenance book, so that all can be registered from now on. In this is unfortunately not when I have to go back to a maintenance. Can one help me there ? When do I have to keep the Twingo waiting again small / large maintenance ?! Would be nice if you could help me there further many thanks ! MFG Japi936
