i have never owned a glanza/gt but have owned a na starlet. all i can say is that there not as comfortable compared to a celica and bits are a lot more expensive. On the plus side glanza/gt are very quick cars. my bf had a glanza (150,000km)he needed a new clutch whilst owning it, decided to go for a exedy clutch with a lightened cusco flywheel, cost him £800 alone without getting it fitted. i know he replaced the crank shaft oil seals too. my mate had a 400bhp gt (5efte)was crazy quick but was consistantly spending money on it. If you have the money i would recommend one though, there fun nippy cars. if you decide to join any of the starlet forums join up with uksc rather than tgtt.
if you are considering buying one, watch out for the crankshaft oil seals, low conpression smoky engines, valve stem oil seals. If someone has fitted a fcd without a fpr engine will run lean. 1bar + on standard internals and turbo is a risk. cracked heads due to unsuported mani/turbo/downpipe. if there is accesive oil vapour round the dumpvalve the turbo seals may be on there way out. hope this info helps hun. if you see one your unsure of post up a link and i will get my bf to give a verdict
