I lived in a hilly area when I had the Telstar, and it would need at least 10-15 minutes warm up time to make it up the driveway; unreliable if in a hurry.
Odometer tampered with; make sure the numbers are perfectly aligned before considering.
Alternator exploded; fragments almost punctured the radiator and hoses.
3 speed auto gave me 460km out of a full 55L tank on 4 separate occasions; get a manual transmission if available.
Had to remove a lot of rust.
Plastic interior turns to grainy sand composition over time.
No power whatsoever; a TX5 is a better alternative.
Whenever I left the Telstar unattended, people would attempt to pick the lock with teaspoons, so I accumulated a vast collection of 20 or so spoons in first 2 months of owning, so visually the locks look flimsy I guess?
