I have a 97 ST-GDI 1800 Manual, non turbo.. reliable as eh!! I got 850kms out of one fill this week.. on average about 750km/fill.
Only problems I've had...
Aircon pump blew.. no biggie to replace, about 180 for a recon unit

One of the metal gear linkage arms snapped (dunno the proper name for them sorry), but I'm guessing the previous owner was a bit of a thrasher.
Good on tyres (depends more on the tires than anything though

)
They sit on the road bloody nicely, not too firm not too soft... just right.
Parts for them are a dime a dozen from what I'm told.
I've done well over 100,000kms in mine over the last 2 years and I still enjoy driving it.
The cams are a bit noisy when idling though... there is stuff you get from Repco etc. which quietens it.
