I was looking at these very closely to replace my current car around next spring. Was either this or a Focus RS or possibly an ST.
Thing that puts me off:
-These still command quite a high price
-Insurance is much higher on these than a Focus RS. Might not be a problem for you. I'm still 20 will be 21 by the time I get around to looking at one.
-Engine is brilliant although doesn't tune as well as a turbo'd one obviously and I already have a revvy cam'd zetec not sure I want another revvy N/A motor want to be a fat lazy shit with a turbo

-Mods can make it see 250-260bhp but expensive.
Other than that, I really like these, think they look absolutely fantastic, sound good, people I have spoken to say they handle absolutely spot on and are actually pretty quick, quicker than you might expect. Price and insurance is what is putting me off one compared to an RS or ST.
