my GTzed is a 53 plate with 104000 miles, hardly any problems...new fly wheel at 80 thats all, you don't to worry ou there they are as good a car at 100k as they are at 1k!!
i've had mine 5 years this month & have put 95 of the 104k miles on it, it needs replacing now though 'cos i do lots of business miles so watch out in the ad page as i will be saying goodbye to it in December, looking then for an 08 or 09 plate then.
if anyone hears of any deals please let me know - i might trade it or sell it private, if anyone knows of anyone wanting a good present for Christmas...at the right price of course, please reply
