ST183 Celica Convertible - What's it worth?

[TheTank]

Hi all. Basically I've been offered an opportunity to purchase a 1991 UK reg automatic convertible Celica, originally from Japan. I haven't viewed it yet, but I'm told it's be sitting up for 9 years and needs a respray, service, and test. It starts and drives, and while wasn't on my most wanted list, it could easily become a tidy startup project to get into the classic scene, where I aim to be shortly. I plan to get it registered as a classic in Ireland once it gets to 30 years old as the VRT is far cheaper, as is insurance.

My question is this though. With good paint, driving great, with perfect interior, the necessary test or paperwork to make for classic yet affordable motoring - what would the average value of these be, might anyone know?

Yes I know it may not be everyone's cup of tea, but the more I read of them, the rarer they are to find for someone who would like one. What value would you put on one restored to great condition?
