It started to rust, but what do you expect after 14 years in the rain?
Rear shock absorber dishes had to be replaced in 1998, due to rust.
The front exhaust pipe broke while on holiday in Southern England. Note: do not drive through Cheddar Gorge without a working muffler! ;-)
The exhaust was replaced by a Toyota dealer in Bristol, on a Sunday, fitted free of charge. Impressive.
Steering universal joint froze, making steering very stiff. Common fault on Starlets of this age - easily rectified at first by a general dose of WD40. Eventually fixed by fitting a replacement from a low mileage specimen in a junkyard.
Main light switch on the column stalk failed. Common on all Toyota's of this age. Replacement column stalk from junkyard fixed it.
Otherwise, the car was totally reliable.
