if she's not rusted i'd offer up to 1.5 for her, but from what i can see it would seem she's been standing for quite some time now and will require a TON of work. i'd try my luck and offer 60-70k and see what happens from there. expect to pay at least 2 lacs on top to get her running and on the road again.
There are only 8 on the road in PK as far as we (VWCOP) know so these cars are quite rare and worth restoring. specially since she is a late model 182 (RHD) which are considered VERY collectable in the UK. if you decide to buy it, i can send you a list of all the possible parts you'd ever need for it (excel sheet) so you can then decide what to buy when.
BTW if that roof isn't cracked & the guy is willing to sell it seperately i'll offer him 10000rs right now for it (can negotiate slightly).
