My son has a metabolic disorder that leaves him highly heat sensitive. We live half an hour from the hospital where he gets his treatment, but my car's AC is not strong enough to handle the 100+ degree heat and grueling sunshine of the central valley. I had planned to buy a Prius before we got his diagnosis. But I've been warned that a car that is optimized for fuel economy may not be optimized for AC strength. The strength of the AC system now trumps any other criterion for choosing a car. Are there any Prius owners here from REALLY hot parts of the country who can advise me? Can I buy a Prius?
