Thanka a lot iRage for the comprehensive answer.
Yes I was reffering to p90 series. Last week I checked a 1.5 RS, with all the features. Everything is in perfect condition except the check engine light is not showing at all. It seems the indicator bulb is removed. When I suggest him to get it verified with the agents, he show no interest. So I decided to avoid it.
Then I came across these 1.3 variants and wonder whether they are worth buying.
These information will surely help me for a better buy. Thanks again. ?
