Requesting help with creating an SQL query to select similar records

This is a little hard to explain but I will do my best.  I need to write/update the example query below  so that it will return the records requested, but also return records based on what was returned. In my example below, two records are returned with "carnumber 55". I want to show those 2 records, but also any other records with the same "carname". In my example below, 3 additional records are displayed because they have the same car name as those returned from the original query. Can someone assist?

Select id, carnumber, carname
from tblOne 
where carnumber = 55

What I want returned from the new query

id   |   carnumber   |   carname
1    |      55       |   bobs car
5    |      55       |   johns car
7    |      88       |   bobs car
8    |      77       |   bobs car
21   |      97       |   johns car
