Hello all! only me again!

I hope everyone had a good crimbo!

Now (i hope not to sound too much of an idiot here) but, i am in need of some decent advice , i have basically been after a smaller enduro bike for this years green laning and i had a dealer call me back about a swap with the tenere, and i just want some others opinions and help if poss on it as i'm not feeling too confident about what has been offered...

Basically the bike is an apparent 2007 wr450f (non ally frame?) that he offered to trade, i'm thinking it could be an 06 or even older! just made road legal some year/s later? Here is a pic of it:

I'm hoping someone here may be able to tell from the pic which model it may be? Googling told me it's no newer than an 06 model even though like i say its on a 07 plate. The asking price is �3,295... what do you guys think?

He offered to deliver the bike and collect the tenere, and settle the "difference" for �500... stating mines only worth 3,6ish even though its a 09 bike with just over 3200 miles and immaculate condition :/ Is he right?

I'm just a little unsure where to go from here, i need to ask the mileage on that WR (went out my head when they called! silly me!) and give it a good check over i think as i havent seen the bike for myself yet, only pictures from the dealers website...

What do you guys think? Being taken for a ride or? terrible pun i know.

Thanks for any help! Really greatly appreciated as always.
