Very little! Once it went totally mad on start up -all I did was disconnect the battery for 2 minutes and it re-set the ECU - problem solved.
The back seats are very flimsy and poor quailty, but I can live with it.
Paid £2500 for a 4 year old car -has to be the best bargain on the planet (and it came with FULL renault history) 1 company owner. Very comfy and the 1.8 16v engine is very sweet. As a bargain run around it is perfect. Additionally it has all the toys you would ever need, Aircon, CD, Electric Roof etc. I had a look recently to replace it with a £5000 budget, but have decided that I shall keep it for at least another year.
Just noticed your comments whilst going through the Renault pages and I don't understand... if you're so happy with the car:
1) Why the long face, and
2) Why would you not have another one?
