Ok, on both of em (not including gas...):
96 GL Zetec ATX: Well over $3000 in the 1.5yrs I drove it (owned 2 years, but 6 months of BMT/tech school it sat). A third of that was the parts/labor for the slapping timing belt/tensioners and WP just for preventive maintainance (that started leaking a couple months later
). 1.5yrs of driving and almost 50K miles later (160K on the odo) I traded it in with a knocking engine and both tranny and engine having overheating problems. Should have kept it, though. I bet I could have got it to 200K with not too much more trouble, which is more use than the $700 I got out of it.
98 SVT: $2000 in it so far in the 3.5 months I've driven it (owned 6 months). $1700 of that was the
tranny.
Guess I like em too much!
EDIT: again, not counting gas, but stealing someone else's idea, the GL cost $0.06 per mile; SVT cost $0.20 per mile (10,000 miles so far I've put on it... 2 trips to Iowa and back included there)
I don't have the time to deal w/ an unreliable car....
