Until the last minute achievement?
 

how to get this achievement?

60 mins is time limit above in repair session so I put 50mins and no achievement pop so i put 57 mins again nothing and i did 60mins again nothing?

I don't understand how get it work, please help?

Not sure what your doing wrong,had no problem with the achievement myself.You are pressing the start button to carry out the repairs?

You need to make sure you are actually doing the repairs. There has to be less than 10 minutes remaining once you have carried out the repairs for the achievement to pop.

You have to do the repairs manually with less than 10 mins remaining, instead of presing the 'y' button to auto repair. (You can check how much time it will take to repair the car by pressing the 'y' button and if less than 10 mins are remaining you can then do it manually before confirming by the start button.)

i have never done them manually, i just did auto repair each time and it unlocked, i wasn't going for that achievement either so im not sure how i did it but i always used auto repair because it was quicker for me.

I just used the y every time - make sure u have the damage switched on ;-)

Same here i got this the first time i ever repaired a car by auto repairing. Maybe your achievements glitched out.
