What's it worth? (BMW content)

[rtha6551]

Hello,

I swapped my Astravan for a BMW 316ti with the intention of selling it on as I don't really want one plus it'd be ridiculously expensive on insurance and fuel. It was the only reasonable offer I'd had in about a month of it being on eBay, Gumtree and Pistonheads hence why I swapped my van for a car I'm not too keen on, as I have the HDi anyway the car I really wanted.

But I have no idea as to what it's 'really' worth. It has:

• 1.8 petrol engine
  
• 140k miles
  
• Leather front seats
  
• 6 disc changer in boot w/aftermarket head unit
  
• Carbon fibre wrapped bonnet/spoiler/door pillars
  
• Carbon dipped filler cap/dashboard
  
• 16" BMW alloys in matte black
  
• 02 plate
  
• MOT till September, tax until December
  

I've put it up for £1000 but I think that might be a bit high for a car that's knocking on a bit now and has a considerably high mileage for a petrol unit :/

Opinions on how I should price it anyone?

Thanks
