The Department of Transport will be introducing a new scheme known as Electronic Vehicle Identification (EVI) as early as 2007. This records, amongst other things, the speed of the vehicle. Talk about big brother.

If this EVI scheme is introduced, then the residual values of cars registered between 2004 and 2007 will rise, as they are not likely to retrofit the chips. I would also probably not have my licence.

Make a note to keep an eye on the introduction date, as you may want to replace your car before then, or keep it. Invariably, the general election and delays will probably mean they can't introduce it until later.
