Yes, you can. If you need a SPARK car for a longer period, you can choose a long-term offer from SPARK. When a daily pack is activated, the SPARK Pro subscription is paused. 

For example: 

With an active SPARK Pro weekly subscription that starts at 12:00 on a Monday, your next payment will be at 12:00 the following Monday. 

If you choose a 2-day package with 200 km included on Saturday, your SPARK Pro subscription will be suspended from the start of the long-term package until the end of the session. 

Your SPARK Pro subscription will be renewed when you complete your session and will be extended by the same number of days that were included in the selected long-term package. 

In the 2-day example given, your SPARK Pro subscription will be extended by 2 days, so your next payment will be due on Wednesday instead of Monday.
