value my carrrrr

[samass]

right, dunno if this goes in here or not, bu ho hum, mods can move if they feel the need

basically, had a guy leave a note on my car asking me if i would sell my car, had a chat to him, and decided we'd both go away, value it and then talk numbers.
he has one thats the same, other than its a 1.6 xl, and he says the body is mint, but the engine is gone (headgasket, i know, easy enough to sort, but cba telling him that, he's already ripped the engine out). his idea is to make one mint car out of two

my project thread is http://www.306oc.co.uk/forum/viewtopic.php?f=20&t=1841, and some of you have seen her at Ace.

stats are as follows

'98 5 door venetian green xsi

shell: 101k

body work: ish, few scratches, rear passenger door and rear quarter are the worst, my sister got a quote of £200 to sort it a while back
inerior: standard cloth, and mint, bar steering wheel
