it's your decision...but you don't want to get the car just in time for the winter, so you're buying a motorcycle?
also there's only been 1 recall (and that's only on the first few 100 SS's built)...the HVAC is a service bulletin...NOT a recall. EVERY car has service bulletins...some have 100's. THIS IS NOT something to freak out about.
good luck trying to order a Z/24.
