Record Funds Set Aside for Car Maintenance

Is there a good way to have an account (in Quicken & the bank), like checking, from which i set $$ aside (in Quicken only) for Car Maintenance?

I tried an "Offline account" in Quicken, but when i create a transfer from the checking to the offline acct, the checking acct value deviates from the bank value.

Thanks in advance for the suggestions!
