Newbie, Going to look at a Celica, what to look for? Options

[1996GT]

Hello,
My son has fallen into the trap of the Celica Gen6 and we are going to look at one soon,
its a low mileage (Show Car) 1996 GT, Dry stored for the last 3 years only being driven for shows and to keep
everything moving and working well, bills for over £3k in that time, Good MOT history online,
full service history? seems to be a much loved motor, owned by a older gent as well..

He wants strong money for it but if its as good as he says then it should last for a good long while..

I have no experience with this car make or model, but I do know my way around a car, is there
any specifics that will need to be carefully looked at, and is there anything I need to listen for as well
as look for, any advice would be gratefully received..

Thanks,
GT..

It should be the ST202, you can find the chassis code stamped on the firewall in about one inch tall characters to confirm it plus there should be stickers in the engine bay for things like the emission system and etc... that'll give the engine designation. That and I think the engine itself has a plate on the intake with "2000 Twin Cam" or something to that effect.
