sounds a bit pricey to me, but if it's a good one, it might be worth it. Negotiate the price down and remember its going to need a cambelt pretty soon despite the mileage (guessing a 54 reg??)
and 36k, have the brakes been changed, has the aux belt been done, how much meat on the tyres, how much tax left etc?
This month mine's had the 48k and years tax done so that's the best part of £420, tyres due next next week so about another £150 to 175 ish for a pair at a guess, brakes need doing and cambelt end of the year. so at a guess petrol, insurance aside I will have spent wrong side of about £1300 on bits and bobs this year. Add that to the price and it starts to look like a bad idea lol
