Not exactly but I used to have a 2001 MK3 2.0 Zetec and have just got a 2009 MK4 2.0 Titanium. The engine is pretty much the same, as is MPG, mine both average(d) 34-36. The 2.0 has a bit more poke than the 1.8, you should feel a difference. The MK4 does feel bigger and is bigger inside and out. The MK4 is a much nicer place to be and drives superbly. I looked at a few different ones before buying. Definitely go for a Titanium over a Zetec, much more comfy and a lot less bright silver trim on the dash. A lot of people don’t find the seats as comfy in the MK4s. I ended up paying £6750 for mine, having only done 40k miles, with a full main dealer history.
