Guy's, Just found this car earlier today, what should i be paying for it? Whats it worth?

1996 - N plate
117k, but 21 stamps in service book
Every MOT
Every tax disc
Mint inside and out
New clifford 600 alarm
4 mint tyres (toyo)
Unused spare/ashtray etc etc

Faults:
Noisy tappets, but drives sound and really tight
Missins the 2 spoiler trims off the bottom of rear bumper (easy fix)

Cheers for any help.
Stu
