Try it's

if object_id('tempdb.dbo.#temp') is not null
drop table #temp

create table #temp (name varchar(100),model varchar(100))

insert into #temp values('Bob','Camry')
insert into #temp values('Bob','Civic')
insert into #temp values('Bob','Prius')
insert into #temp values('Kevin','Focus')
insert into #temp values('Kevin','Civic')
insert into #temp values('Mark','Civic')
insert into #temp values('Lisa','Focus')
insert into #temp values('Lisa','Civic')

select row_number() over(partition by name order by (select null)) as n,
row_number() over(partition by model order by (select null)) as m,*
from #temp) as a
