I didn't do enough mileage to notice the low MPG, but the TAX was £550 for 12 months (I believe a few early MK5 models will be in the older / lower tax bracket), mine was also coming up to needing a service which again was circa £500.
The main reason I disliked it was due to the lack of power, my friend bought a 2005 Leon Cupra R around about the same time, and we had a 30mph rolling start race up to 130mph (on my private runway) and his car managed to get a car length on me in standard form. I also don't think it performs well enough to warrant the four wheel drive system.
Pros:
Prestige looks
Amazing sound track, even with the OEM exhaust
Cons (compared to an ED30)
Lower MPG
Heavy 4wd system
Heavy engine
High Tax Bracket
High Servicing costs
Less Torque
Slower
