I'm sure some of these questions have been answered but others probably not:

1) I recently moved and I'm not sure when the recall letter will be sent out to my area. should I just take it in and ask anytime? or wait a bit?

2) what's the situation with aftermarket parts? I know stuff such as intake and exhuast parts should be left alone, but what about something like pully? not sure if that would actually be any problem, but just wondering.

3) how long should I expect them to keep my car? do they always do the spark plug replacements and such?

Sorry for any reposted questions, thank you for info/answers
