Suzuki Grand vitara Valuation help

[jimbodeeni]

Hi all, I bought an 03 facelift LWB silver Grand vitara last year with the intention of prepping it for laning etc. But I wont be able to put the time or money into it as I had wished and the time has come to sell, has only been used for commuting and is in great condition.
Spec:
16 alloys
AC
Full leather (which I believe is quite rare)
4 x brand new Cooper discoverer AT3 as previous tyres were the originals and starting to perish and they come with 50,000 mile warranty.
Upgraded kenwood CD/MP3 player with aux input
57000 miles on clock
Just had major service done with the following:
new gearbox oil
new transfer box oil
new brake fluid
new coolant
Front and rear diffs have had new oil
new oil filter
new air filter

Also had the car fully checked over to ensure car was top condition,
the only thing that flagged up was that the seal was starting to wear on clutch slave cylinder
so Brand new slave cylinder was fitted.

Car has 11 months MOT too and sailed through, Have full VOSA history and has never failed an MOT apart from one which was due to incorrect spacing on a private plate that was fitted by a previous owner.

Car is in cracking condition

Have no idea what to put it up for sale for?
cant find any for sale with the leather interior at the moment to compare either.

Your help would be greatly appreciated.
THANKS
