im 6.1 too, when i was looking for a glanza i found that head room was great as you can whinde the seat down. but leg room was different from 1996 glanza to 1998-9 glanza as the seats were different as standard, so in the 1996 glanza you had half an inch or so more available leg thean the 1998. half and inch or so may seem minimal, but everyone style of how they place there right foot on the brake and gas pedals can differ. i didnt sample GTs as it wasnt what i was looking for, but jus thought id give my 2pence of info.
