Leaks terribly.
Bad fuel pump.
Needed rebuilt front suspension, new front seat.
Needs new door and trunk seals.
A good sized car, but a little cramped for larger people.
Access to the trunk is not great.
Back seat useable, but not especially comfortable for adults.
Steering wheel not as comfortable to hold as it could be (shape doesn't conform to hand well).
2-speed automatic transmission is not the best... it really needs a three speed for best performance.
I used to have a '61 Comet S-22 (loved those crazy cat's-eye taillights they used, only in 1960-61). The S-22 was the "sporty" coupe version of the Comet which came with bucket seats, center "console", red-painted wheels and other such accessories to distinguish it from the regular Comets. Same old low-power six-cyl engine though.
