Renault Twingo 94, and ask a few questions.

We have seen a Twingo that we would like to buy, it is a year of construction 94 and has run 170 thousand. The car is well cared for in itself, but it also has a few defects. And indeed the engine sweats under the head,completely long ago, but the head seal is ok,is that something bad,or eventuel a broken seal,e.g. on the side ? Dan has it unfortunately only Euro 1, there is a possibility to get it on Euro 2,hope that is possible with the Twingo 1239 ccm with 40 KW Had a VW Polo before that true any such an import vehicle from Spain for it there was no cat or Twin Tec, because he had a naughty key number. So that was for the first time, looking forward to answers.
