Cheers mate
It is nice to give something back to the forum after all the advice and questions I have had 
Yeah - thanks for that! Having never been in an accident its nice to have someone who knows what they're talking about around!
I called Accident Exchange today - and told them that I didn't want a wrecked car!!!
The lady on the phone was very nice and said that they can arrange to have the car salvaged for me and get me the money for it. I told her even with their £13k and £3k that I was looking for more than £16k. She asked me to send in examples of cars etc (which I'd already done last night) and then said she'd find the email I sent in and get it linked. She'd then contact the guys insurance and tell them that I need more.
She asked if I always buy from a main dealer - which I said YES. She said this is good because if I buy from a main dealer, then the price will be more. I told her that I bought that car new for a few pence less than £25k about 20 months ago, and that I need about £18 for a decent replacement. I also explained that after buying a repaired write off car (wasn't listed in HPI) that I'll never buy a second hand car again, and that I'll be buying a brand new one. She advised me not to cash their cheque for the time being (if I get one!) and they'd get back to me soon.
I'll save all your lines for later when they come back to me with the next crummy offer!
If I do threaten to make a complaint - who is it I say I'm complaining to by the way?!
I wish I'd taken GAP insurance - but as they gave me 1 year free, I didn't see the need! I'll definately be taking it on my next car!
