if it was me and had money to burn, id get one like garys ( st205 )
they run about the 35 thousand mark last look and are pretty hard to get but they are true king hitters .. they are by far the BEST no questions asked celica ever built ..
power wise they piss on WRX's and evo's ( bar the latest STI's and Evo 7's ) and have a higher again level of build quality
sadly most of the cxarlos sainz ones - unless owned by enthusiasts - may have had rally life - ie used as a rallycar - then connverted back after the usage period came up ..
keep your eyes peeled - i only have ever seen 2 clean original and certified versions - and both owners wont part with them even for over market value ( believe me i asked !! )
