Group a measure into different portions

[Datagulf]

I have a measure that checks how long a car has been in a garage in terms of Days. 

Days Elapsed in Garage=
DATEDIFF(
SELECTEDVALUE(cars_repair[entry_date]),
SELECTEDVALUE(Cars_repair[date_completed]),DAY
)

So the number of vehicles is too many and I want to group them into smaller groups like
less than 30 days, 30 to 60 days, 60 days to 90 days, more than 90 days. This will reduce the number of those entries when displayed in a table. How do I do this?

@Datagulf , Bucketing of measure needs independent table
