[the way scene tax seems to work is irrespective of age, condition, mileage or model it works by you thinking of a number [any number mind] double it, take away 5 then treble it, take away 4 and quadripple it then take a £5 off for cash should be about right if thats to hard simply look up ebay find a comparible model/yr/milage and treble its cost should get the desired results
Anyone paying thats ort of money needs their head looked at you can buy a T5 [base model 1.9tdi] brandnew or ex demo for that kind of dosh ????
