Before I acquired my BMax 1.0 there were concerns in my mind about the longevity of such a small 3 cylinder engine. Looks like those concerns were unnecessary. There is a BMax 125 Zetec on a 65 plate for sale in Autotrader with 140,000 miles on the clock. My maths say that that it equates to 20,000 per year. Whoever had it originally obviously had no worries. My assumption is of course that it is the original engine.
