You can go down to Qual-com Stadium where the Chargers play, there are all kinds of cars that race there every weekend. I used to be stationed in Coronado and went to the local Mopar club's cruise a few times. I went to one monthly meeting and was done with it. There is a reason I don't like clubs and they are the epitomy.
Do a Google search for San Diego Mopar club and see if you can make one of the cruise ins. They do have some nice mopars.
