MVC more specified models should be populated by more precise query too?

Performance

If you have a Car model with 20 or so properties (and several table joins) for a carDetail page then your LINQ to SQL query will be quite large.

If you have a carListing page which uses under 5 properties (all from 1 table) then you use a CarSummary model. Should the CarSummary model be populated using the same query as the Car model?

Or should you use a separate LINQ to SQL query which would be more precise?

I am just thinking of performance but LINQ uses lazy loading anyway so I am wondering if this is an issue or not.
