Sarcasm not needed - there are a couple of models of renault which have legendary reliability if serviced correctly:
* Renault 4 - you can still see them running in southern Europe till this day. If serviced correctly it will continue to run.
* Clio MK-1, the 1.4 engine - again, I have owned 3 of those over the years in different countries and one of them is still running till this day after I handed it down to relatives. Not bad for a car which has left the assembly line in 1989.
The trick with the old Renaults is to replace every 10 years (or force-flush every 5) the radiator. It gets clogged up, the engine overheats and then you are thanking Renault reliability on the side of the road. There are a couple of ther (lesser) bits which need attention and which you will not find in Haynes or the Renault service manual. If you regularly take care of these an old small(note the emphasis on small) Renault like Twingo Mk1, Clio Mk1, Renault 4 (to a lesser extent 5), etc will run and run.
Renault has always sucked at two things - large cars (on all counts - all variants of Espace have always been a complete and unmitigated disaster) and electronics. As they have stuffed all their new ones with electronics to the gills it has become a definitive disaster at the roadside.
1. Renault has barely caught up with Daihatsu from ~ 2000. My old 2003/2004 Sirions (got two of them, one in UK, one abroad) can do a sub-9m turning circle, comply with pedestrian safety (it is the first car to do so and the car that made the Eu tell the manufacturers to stop claiming it is impossible and change the regs), have a bigger boot, hit 0-60 sub-9s and can go onto a dirt track and offroad (the 4x4 one I keep abroad for that exact purpose).
2. Renault has lost the plot in the area which was its core competency amidst European manufacturers - making small cars that do not suck. If you compare Twingo Mk1 to Peugeot 105 the Twingo wins hands down. Other manufacturers (vw Lupo, 90-es Ford Fiasco, etc) do not come even close. Well... no more... It is a rebadge of the Smart engineering disaster now.
