Hi welcome Alex to the forums And you're in the right place ;)
Feel free to loads some pictures up too if you like
I would say £400 is maybe a little to high £599 that's tax and tested does have 140k on the clock but looks like its been well looked after I've seen one for, I'm not saying your isn't :) but four new tyres being £250 plus car £400 tax M.O.T could end up costing a lot to get back on the road. I would still list it here and where ever you want to I would say you might get £400 from a breaker as the sad fact is the parts of the car is worth more then the car its self :( sorry to say
I'm just trying to sell an 02 Jag V6 with damage no MOT because the fuel pumps had it, but fully repairable at most £400 if you can't do the work yourself , a great car and only after £400 for that. The market seems unless your giving it away people don't really want to know at the min :(
But best of luck with what ever you choose :D
